Let me analyze this task. I need to:

1. Build a side-scrolling platformer in Mario style using Phaser
2. All in one file: index.html
3. CSS in <style> tag, JS in <script> tag
4. No external resources except phaser.min.js which is already present
5. Procedurally generated graphics only (no external images/audio)
6. Features: run, jump, scrolling platforms, stomp enemies, collect coins, reach goal flag

Let me first check the current directory to confirm phaser.min.js is there and understand its structure.

I'll start by examining the current directory and the phaser.min.js file to understand what's available.

Phaser 3.80.1. This is a modern version. Let me build a complete side-scrolling platformer with:

- Procedural graphics (using graphics primitives, drawn textures, or generated sprites)
- Run and jump
- Scrolling platforms (side-scrolling world)
- Stomp enemies
- Collect coins
- Reach goal flag

The challenge with procedural graphics: I need to generate sprites without external images. I can use:
1. `Phaser.GameObjects.Graphics` to draw shapes and convert to textures
2. `generateTexture` or render-to-texture
3. Custom shapes

Let me plan the game:

**Player**: A Mario-style character - red shirt, blue overalls, brown hair. I'll draw this procedurally using Graphics.

**Enemies**: Goomba-like creatures - brown body, white eyes. I'll draw these procedurally.

**Terrain**: Green pipes, brown blocks, blue sky background. Platforms made of tiles or rectangles.

**Coins**: Yellow spinning coins.

**Goal**: A flag on a pole.

Let me think about how to generate these graphics. The cleanest way is to create textures using a Graphics object and `generateTexture`.

Let me structure the code:

```javascript
// Create game config
const config = {
    type: Phaser.AUTO,
    width: 960,
    height: 540,
    parent: 'game',
    physics: {
        default: 'arcade',
        arcade: {
            gravity: { y: 900 },
            debug: false
        }
    },
    scene: [BootScene, PlayScene]
};
```

Actually, let me keep it simpler with a single scene or use a BootScene to generate textures and a PlayScene for gameplay. Let me use multiple scenes for cleanliness.

**Texture generation strategy:**

For each sprite, I'll create a function that draws it on a Graphics object and calls `generateTexture()`.

Let me think about the visuals:

1. **Player (Mario)**: 
   - Red cap, red shirt, blue overalls, brown shoes, skin face
   - I'll draw using rectangles/circles

2. **Goomba**:
   - Brown mushroom-like body, white eyes with black pupils

3. **Coin**:
   - Yellow circle with shading

4. **Flag**:
   - Red/yellow flag on a pole

5. **Brick block**:
   - Brown/red brick pattern

6. **Pipe**:
   - Green pipe

Let me write the code. I'll make it a complete, polished game.

Let me think about the level design. I'll create a tiled level with platforms at various heights. The world scrolls as the player moves. I'll make the level procedurally generated (random placement of platforms, coins, enemies) or use a hand-crafted level. For a good Mario-style experience, I'll do a mix - a designed progression of challenges.

Actually, let me make a procedurally generated level that still has structure: ground, some floating platforms, pipes, blocks with coins, enemies positioned along the path, and a flag at the end.

Let me design the level as an array of platform segments, or generate platforms with gaps that the player must jump across. I'll make it deterministic-ish but with some random elements.

Let me think about controls:
- Arrow keys / A D + W Space for jump
- Hold jump for higher jumps (variable jump height)
- Run animation

Physics:
- Arcade physics with gravity
- Player can run, jump, fall
- Collisions with platforms
- Enemy collision: player stomps enemy if falling (velocity.y > 0), enemy dies
- If player touches enemy from side/top, player loses a life

Let me write this comprehensively.

Let me structure:

```html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
  html, body { margin:0; padding:0; overflow:hidden; background:#000; height:100%; }
  #game { width:100%; height:100%; }
  ... some UI overlay styles
</style>
</head>
<body>
<div id="game"></div>
<script src="phaser.min.js"></script>
<script>
  // Phaser game code
</script>
</body>
</html>
```

Let me now write the full game code. This will be substantial. Let me think through each component carefully.

### Graphics Generation

I'll create a helper that draws each sprite:

```javascript
function generateTextures(scene) {
    const gfx = scene.add.graphics();
    
    // Player - draw Mario
    gfx.clear();
    drawMario(gfx);
    gfx.generateTexture('player', 32, 48);
    
    // ...
}
```

Actually, for animations, I might want the player to have run frames. But to keep things manageable with pure procedural graphics, I could either:
- Animate by drawing a few frames and cycling
- Keep it simple with one pose but add movement effects (squash/stretch, facing direction)

Let me create a few frames for running animation - maybe 2 frames to keep it manageable, plus idle and jump frames. Actually, let me do a proper run cycle with 2 frames.

Hmm, drawing multiple detailed frames is time-consuming. Let me do a cleaner approach:
- Player walk cycle: 2 frames
- Idle: 1 frame
- Jump: 1 frame
- Hurt: 1 frame

Let me draw Mario-ish character. I'll make it recognizable: red cap, red shirt, blue overalls, brown shoes, pale skin face, black hair.

Let me define a function that draws Mario at a given frame (0 = idle, 1 = walk frame 1, 2 = walk frame 2, 3 = jump/hurt).

Actually, let me simplify the animation: I'll draw 2 walk frames and reuse. Let me focus on making it look good.

Let me write the drawing functions. I'll use a coordinate system centered.

For Mario:
```
Frame: idle/walk1/walk2
- Head: skin-colored oval
- Hair: black
- Cap: red
- Body: red shirt + blue overalls
- Arms/legs: vary between frames
```

This is getting complex. Let me write it carefully with absolute positions relative to sprite.

Let me think about a cleaner design. I'll define the player as a set of body parts with positions, and animate the limbs by frame.

Actually, let me create a Mario sprite that's 32x48 pixels. Let me draw frame by frame.

Let me write helper functions. I'll draw on a Graphics object.

Let me just write the whole thing. I'll be systematic.

#### Player sprite (32x48)

Mario facing right:
- Feet at bottom: brown shoes (2 rectangles)
- Legs: blue (overalls) or red pants? In Mario, the overalls are on top of red shirt. Let me do: red shirt visible at top, blue overalls straps going down.
- Actually classic Mario: red cap, red shirt, blue overalls (straps), blue overalls pockets, brown shoes, flesh face, black hair, white gloves.

Let me draw:
- Head/faces: flesh circle/oval (x center)
- Hair: black hair peeking from cap
- Cap: red, with cap brim
- Eyes: black dots, white eyes
- Mustache: black
- Shirt: red, neck
- Overalls: blue straps from shoulders, blue body
- Arms: flesh then white gloves
- Legs: blue overalls legs

Let me just draw it.

Positions (32 wide, 48 tall), origin at top-left. Let me draw with a reference.

Let me set up coordinates. I'll draw at specific positions. Let me think in terms of the sprite being 32x48.

For frame 0 (idle):
```
// Shoes - brown
gfx.fillStyle(0x8B4513);
// left foot
gfx.fillRect(4, 36, 8, 6);
// right foot  
gfx.fillRect(20, 36, 8, 6);

// Pants/overalls legs - blue
gfx.fillStyle(0x0000FF);
// left leg
gfx.fillRect(5, 28, 6, 8);
// right leg
gfx.fillRect(21, 28, 6, 8);

// Shirt - red
gfx.fillStyle(0xFF0000);
gfx.fillRect(8, 24, 16, 8);

// Overalls body - blue (over the shirt lower part)
gfx.fillStyle(0x0000FF);
gfx.fillRect(8, 28, 16, 8); // wait that overlaps legs
```

This is getting messy with overlaps. Let me just carefully layer. Actually the order matters - later draws cover earlier. Let me draw from back to front.

Hmm, let me reconsider. For Mario, the classic look: blue overalls over red shirt. The overalls are straps + two front pockets + the suspenders. Let me simplify:

- Red shirt: neck down to waist
- Blue overalls: straps on shoulders + square pockets on front

Let me draw:
Back to front order:
1. Hair (black) - under cap
2. Shirt (red) - neck area
3. Overalls straps (blue)
4. Overalls body (blue) - covering shirt lower
5. Arms (flesh + glove)
6. Legs (blue overalls legs) - wait, the overalls go full leg

OK classic Mario overalls are full-length on legs. Let me do:
- Blue overalls: straps + legs (full leg)
- Red shirt: shows at neck/collar
- Arms: flesh + white glove, red shirt sleeve ends

Let me draw simpler, iconic:
```
Head area (y 0-20):
  - Skin face oval
  - Black hair
  - Red cap
  - Eyes (white/black)
  - Mustache line
Shirt (y 18-30): red
Overalls straps (y 18-26): blue, from shoulders
Overalls body (y 26-36): blue
Arms: skin upper, white glove, red sleeve
Legs (y 32-36): blue overalls legs -> into shoes
Shoes (y 36-44): brown
```

Let me just write reasonable code. The exact look doesn't need to be perfect; it should be recognizable as a Mario-style platformer character.

Let me define the drawing with a scale. I'll draw at a base and scale. Actually let me just use fillRect and fillCircle with specific colors.

Let me establish a color palette:
- Skin: 0xF9D9B8 (light peach) - actually classic Mario uses a peach
- Hair: 0x000000
- Cap red: 0xC0392B or 0x8B0000
- Shirt red: 0x8B0000 (dark red)
- Overalls blue: 0x1E328B or 0x0000AA (bright blue)
- Gloves white: 0xFFFFFF
- Shoes brown: 0x8B4513

Let me draw the player frames. I'll write a function drawPlayer(gfx, frame) where frame is 'idle','walk1','walk2','jump'.

Actually, to make the code manageable, let me define the player with body parts and animate by moving limbs. Let me write it frame by frame but with shared structure.

Let me just write it out. I'll create a function that draws Mario given a frame index 0-3.

Let me write carefully.

```javascript
function drawPlayer(g, f) {
    // f: 0 idle, 1 walk1, 2 walk2, 3 jump
    g.clear();
    const R = (c) => g.fillStyle(c);
    const rec = (x,y,w,h) => g.fillRect(x,y,w,h);
    const circ = (x,y,r) => g.fillCircle(x+r,y+r,r);
    
    // Determine limb positions by frame
    let armL, armR, legL, legR, bodyY;
    if (f === 0) { armL=6; armR=26; legL=8; legR=20; bodyY=26; }
    ...
}
```

Hmm, fillCircle in Phaser Graphics - does it take x,y,r? Yes, `g.fillCircle(x, y, radius)`. But x,y is center. And fillRect takes x,y as top-left.

Let me be careful. Let me just position things with explicit coordinates per frame. This is the most reliable.

Let me define the sprite as 32x48, drawing with origin top-left.

Let me write the player frames with explicit pixel coordinates. I'll make the character roughly 32 wide, 48 tall.

Let me define key body parts and positions:

**Idle frame:**
```
Head (skin): circle center (16, 12), r=8 -> oval... use fillRect for simplicity or ellipse
Cap: red, shape covering head top
Hair: black
```

Let me just carefully lay out pixels. I'll write a function and use rectangles primarily, with circles for head/feet.

OK let me just write the full code now. I'll make it functional and recognizable. Let me get to coding the whole file.

Let me also think about:
- Enemies (Goomba): brown body, white eyes with black pupils, 24x24
- Coin: yellow, 16x16, with spin animation (can use frames or tween rotation)
- Flag: pole + red flag with yellow stripe, at end of level
- Blocks: ? blocks or brick, 32x32, with pattern
- Ground: brown/tan tiles
- Pipes: green cylinders

Let me design the level. I'll make a level ~3000px wide. Ground along the bottom. Platforms floating. Enemies on platforms. Coins in the air. Flag at the end.

I'll generate the level with a mix of fixed ground and procedurally placed floating platforms + challenges. Let me make it structured: a sequence of segments.

Actually, let me make a level that's mostly procedurally generated but with increasing difficulty, ending at the flag. I'll place platforms with gaps to jump over, enemies, coins, pipes.

Let me write a level generator that creates platforms in a chain from left to right, ensuring the player can progress.

Let me think of segments:
- Start area (ground + some blocks with coins)
- Gap (jump across)
- Series of floating platforms
- Pipe obstacles
- Enemy sections
- High platforms
- Flag pole

To keep it reliable, I'll generate platforms in a path: each platform starts within jump range of the previous, with random height. Place enemies/p coins on them.

Let me write a generator:

```javascript
function generateLevel() {
    const platforms = [];
    const enemies = [];
    const coins = [];
    const blocks = [];
    
    // Ground
    platforms.push({x: -500, y: 500, w: 4000, h: 60});
    
    // Floating platforms chain
    let x = 100;
    let y = 380;
    const maxWidth = 2000;
    while (x < maxWidth) {
        const w = random(100, 180);
        const h = random(20, 36);
        const nx = x + random(60, 120);
        // ensure jumpable
        const maxJumpX = 160;
        ...
    }
}
```

This needs care to keep the level solvable. Let me make max horizontal gap reasonable for the player's jump (player can jump ~170px horizontally when running).

Let me set player jump to allow ~180px horizontal gap when running. Max fall height tolerable.

Let me write the generator to keep gaps small.

Actually, let me simplify and make a designed-but-varied level. I'll create a list of platform templates and place them in sequence. This guarantees solvability.

Let me define the level as a sequence of challenges with known-good geometry, and sprinkle procedural coins/enemies.

Hmm, the user said "procedurally generated graphics" (meaning graphics are generated, not from assets), and "side-scrolling platformer". They didn't strictly require procedural level, but "procedurally generated" in my approach to graphics. Let me re-read: "Use ONLY procedurally generated graphics, no external image or audio assets." - This is about graphics/assets, not necessarily the level. But I think a mix is fine. Let me do a level that's designed with some procedural variation.

Let me make the level a fixed-but-interesting design with multiple segments. I'll hand-place platforms for reliable gameplay, and place enemies and coins. This is the safest for a playable game.

Actually let me do a blend: a base level design that I hand-craft for good platforming, but I'll generate the visual details (graphics) procedurally. And I can add randomized coin/enemy placement within the designed platforms. That satisfies "procedurally generated graphics" and is reliably playable.

Let me go with a hand-crafted level for reliability, ~2400px wide, with the flag at the end.

### Game flow
- Player starts at left
- Can die (fall off bottom, or get hit) - restart at beginning or last checkpoint
- Collect coins (score)
- Stomp enemies (score, they disappear)
- Reach flag -> win
- Lives: 3, or just restart on death

Let me add:
- Score tracking
- Lives
- Win/lose screens

Let me keep it focused but complete.

### Technical details

Physics: arcade. Player has velocity, can move left/right, jump (only if on floor / touching down). 

Jump mechanics:
- On jump key press, if player is on ground (touching down via body.onFloor or body.touching.down), set velocity.y = -jumpStrength
- Variable height: while jump key held and velocity.y < 0, apply a bit more upward force or multiply
- Let me implement: when jump key down and velocity.y < 0, apply an extra upward impulse scaled over time, capped.

Let me implement variable jump: 
```
if (jumpKey.isDown && velocity.y < 0) {
    velocity.y -= jumpBoost; // or multiply
}
```
Actually simpler: when jump starts, set vy = jumpVel. Then each frame while key held and vy<0, add small upward (reduce gravity effect). Let me do:
```
if (cursors.space.isDown && player.body.velocity.y < 0) {
    player.body.velocity.y -= 150;  // extra boost while holding
}
```
But cap so it doesn't float. Let me limit boost duration.

Actually a clean variable jump:
```
if (jump pressed and on ground) {
    vy = -600; (initial)
}
if (jump held and vy < 0) {
    vy -= 180 * dt; // small continuous
}
```
with gravity -900... Let me tune. Let me set gravity y=1000, jumpVel=-520, extraHoldBoost applied while holding and vy<0. Let me just test mentally; I'll tune in code.

Let me make player speed: runSpeed = 250, accel. Jump: -550, gravity 1000, maxFall 700. Variable: while holding jump and vy<0, reduce gravity by factor or add upward.

Let me implement variable jump with a counter (coyote time / jump buffer optional). I'll keep coyote time simple.

### Controls
Support both WASD and Arrow keys. Let me use a keys object:
- left: A or ArrowLeft
- right: D or ArrowRight
- jump: W, Space, or ArrowUp
- run: shift? (just always run)

Let me track these.

### Scrolling camera
Use `this.cameras.main.startFollow(player)` and set world bounds.

### Win condition
Reach the flag (overlap with flag zone) -> victory.

### Death
- Fall below world (y > world bottom + 100) -> die
- Get hit by enemy (enemy touches player not from top) -> die
- On death, lose a life, restart. If lives > 0 restart at start. If 0, game over.

Let me add 3 lives and restart.

Let me also handle enemy stomping: when player.velocity.y > 0 (falling) and overlaps enemy and player.bottom <= enemy.top + some tolerance -> stomp enemy, bounce player (vy = -stompBounce), enemy dies.

### Graphics details

Let me make the graphics look decent. I'll draw each texture on a Graphics object.

Let me think about sizes:
- Player: 32x48
- Enemy (Goomba): 32x32
- Coin: 16x16 (will scale or use 24x24)
- Block: 32x32
- Pipe: 32 wide, height variable
- Flag pole: 16 wide, ~200 tall + flag

Let me write all drawing functions.

Let me start coding the full file. I'll write it incrementally but in one go.

Let me draft the structure:

```javascript
// Preload: generate textures
// Create: set up level, player, controls, camera
// Update: input, physics, collisions, win check

const WIDTH=960, HEIGHT=540;
const config = {
    type: Phaser.AUTO,
    width: WIDTH,
    height: HEIGHT,
    parent: 'game',
    backgroundColor: '#5c94fc', // sky blue
    physics: { default:'arcade', arcade:{ gravity:{y:1000}, debug:false, } },
    scene: {
        preload,
        create,
        update
    }
};
const game = new Phaser.Game(config);
```

Let me write the texture generation in create().

Let me define generateTextures():

```javascript
function generateTextures() {
    const g = this.add.graphics({x:0,y:0});
    
    // Sky gradient as background - could draw on a separate graphics covering camera
    
    // Player
    drawPlayerFrames(g);
    g.generateTexture('player-idle', 32, 48);
    // ... hmm generateTexture generates from current graphics content. Need separate calls per frame.
}
```

Actually `generateTexture(key, w, h)` captures the graphics current state into a texture. So for each frame, I clear, draw the frame, then generateTexture to a different key. But generateTexture uses the graphics' render. Let me do:

```javascript
function generateTextures(scene) {
    const g = scene.add.graphics({ x: 0, y: 0 });
    
    // player frames
    g.clear(); drawPlayerIdle(g); g.generateTexture('player-idle', 32, 48);
    g.clear(); drawPlayerWalk1(g); g.generateTexture('player-walk1', 32, 48);
    g.clear(); drawPlayerWalk2(g); g.generateTexture('player-walk2', 32, 48);
    g.clear(); drawPlayerJump(g); g.generateTexture('player-jump', 32, 48);
    
    // enemy
    g.clear(); drawGoomba(g); g.generateTexture('enemy', 32, 32);
    
    // coin frames
    g.clear(); drawCoinFrame(g,0); g.generateTexture('coin-0', 16, 16);
    g.clear(); drawCoinFrame(g,1); g.generateTexture('coin-1', 16, 16);
    // ... or just spin coin via tween
    
    // block
    g.clear(); drawBlock(g); g.generateTexture('block', 32, 32);
    
    // ground tile
    g.clear(); drawGround(g); g.generateTexture('ground', 32, 32);
    
    // pipe
    g.clear(); drawPipe(g); g.generateTexture('pipe', 32, 32); // hmm pipe taller
    
    // flag
    ...
}
```

Wait, generateTexture - the signature is `generateTexture(key, width, height)`. It generates a texture the size of the graphics object? Actually it captures what's drawn. The width/height specify texture dimensions. Good.

But there's a subtlety: the Graphics object position matters. If I draw at positive coords it should be fine. Let me keep g at (0,0) and draw within positive coordinates.

Hmm, actually generateTexture on a Graphics - I recall you might need draw the graphics content and it captures at (0,0) of the graphics. Let me just draw with coords starting near 0. For a 32x48 sprite, I draw from (0,0) to (32,48). But I want to center the character visually. I can just draw within the 32x48 box. For the player, the head near top, feet near bottom.

But the character might look better if slightly offset. It's fine.

Let me reconsider: When you call `g.generateTexture('key', 32, 48)`, the texture is 32x48, and the graphics is rendered into it at the graphics' local position (0,0 of graphics maps to 0,0 of texture, and only the content within 0..32, 0..48 is captured—actually it captures all drawn content rendered at its offset). To be safe, I'll draw all content within [0,32]x[0,48].

For the player, I'll position arms/legs within bounds, maybe allow slight overflow then it's clipped.

Let me now write the actual drawing functions with coordinates. This is the bulk of the work.

#### drawPlayerIdle(g): Mario 32x48, facing right, neutral pose

Colors:
- SKIN = 0xF9D9B8... hmm classic Mario skin is more like 0xFFB884? Let me use 0xF4C89E or 0xFFFFFF-ish. Actually let me use a tan: 0xE8C08E? Let me pick 0xF5D0A9.

Hmm, let me just pick reasonable colors:
- CAP_RED = 0xCE1126 (classic Mario red) - or 0xC0392B
- SHIRT = 0xC0392B (same red, darker)
- OVERALL_BLUE = 0x264653? No, Mario blue is bright: 0x2A6FDB or 0x1565C0. Let me use 0x1E88E5 (bright blue) -> actually Mario overall is more like 0x0000FF bright. Let me use 0x1565C0 (deep blue/indigo). I'll use a vibrant blue: 0x2A6FDB.

Hmm, I want it to look Mario-ish. Let me use:
- cap/shirt red: 0x9B1B2B? Too dark. Let me do 0xCE1126 for cap (bright) and 0x9B1B2B (darker red) for shirt.

Actually, simpler: cap = 0xC0392B, shirt = 0x8B0000, overalls = 0x0000A0 (strong blue), gloves = 0xFFFFFF, shoes = 0x654321, skin = 0xF4C89E, hair = 0x000000, eyes black = 0x000000.

Let me lay out the idle frame. I'll draw using fillRect/fillCircle.

Let me think body proportions. Head ~ hair at y 2-14, cap over hair. Face ~ oval. Shirt neck. Overalls. Arms down. Legs.

Let me write coordinates (top-left origin):

```
skin face: ellipse centered ~ (16, 13), size ~ 14x16 -> fillEllipse(16,14, 14,16)
hair: black, at top of head / under cap
cap: red, dome + brim
eyes: white then black pupils - or just black dots for simplicity
mustache: horizontal black line near y 19
shirt: red neck rectangle at top
overalls straps: blue from neck sides
overalls body: blue
arms: flesh upper arm + white glove, red sleeve
hands down at sides
legs: blue overalls legs
shoes: brown
```

Let me write it. I'll write a helper within draw function.

This is a lot. Let me just carefully write each frame. For walk animation, I'll move the arms and legs. Let me define frames:

Frame idle: arms straight down, legs together.

Frame walk1: left arm forward/up a bit, right arm back; right leg forward... etc. Let me just offset.

Actually let me define a parametric approach: define body part positions for each frame as objects, then a single draw function that takes positions. That reduces code.

```javascript
function drawPlayer(g, pose) {
    g.clear();
    const {
        capX, capY, faceX, faceY,
        armL, armR, legL, legR, ...
    } = pose;
    ...
}
```

Hmm, but cap/face shape is the same; only limbs move. Let me separate: a base body (head, cap, face, shirt) that's constant, plus limbs (arms, legs) that move per frame.

Let me write:

```javascript
function drawPlayerBase(g) {
    // head/face/cap/shirt (the non-moving upper body)
    // draw on graphics g
}
function drawPlayerLimbs(g, armLAngle, armRAngle, legLAngle, legRAngle) {
    // draw arms/legs as lines or rects rotated
}
```

But Graphics rotation of individual parts is tricky without transforms. I can use g.save()/g.translate()/g.rotate(). Graphics supports save/restore/transforms. Let me use that.

```javascript
g.save();
g.translate(x0, y0);
g.rotate(angle);
g.fillRect(0,0,w,h);
g.restore();
```

Yes! Phaser Graphics supports transform stack. Great, this makes limbs easy.

Let me design the player as connected parts with a transform hierarchy:
- Body anchor at shoulders (around x=16, y=26)
- Arms: pivot at shoulder, rotate
- Legs: pivot at hip, rotate

But to keep it from getting complicated, let me just draw each limb with absolute transformed position using translate+rotate, with a pivot at shoulder/hip.

Let me define limb endpoints:
- Upper arm from shoulder to elbow
- Lower arm from elbow to glove
- Thigh from hip to knee
- Shin from knee to shoe

This is like a character rig. Could be elaborate. Let me do a simpler stick-ish but filled approach.

Given the resolution (32x48) and 8px per tile world, let me keep limbs as simple rectangles (2-3 px wide) rotated. Let me rig:

Shoulder (left): approx (14, 24)
Shoulder (right): approx (18, 24)
Hip: approx (16, 30)
 ankle area.

Hmm let me just go with filled rectangles representing limbs, pivoting at shoulder/hip.

Let me simplify the character to be blocky but readable:

Body: red shirt + blue overalls. Let me treat torso as the constant part.

Let me write the player draw function using transforms for arms/legs. I'll do it carefully.

Actually, you know what, given time constraints, let me make a clean 2-frame walk cycle by manually specifying pixel positions rather than a rig. It's more reliable. Let me draw each frame completely with explicit rects.

Let me define the player as 32 wide, 48 tall. I'll write drawPlayer(g, frame) that draws the whole sprite for that frame.

Let me carefully choose coordinates. I'll iterate.

I'll define the pose as a set of part positions. Let me define a data structure:

```javascript
function playerPose(frame) {
  // returns part positions
}
```

OK I'm overcomplicating. Let me just write 4 drawing blocks with explicit coordinates. Let me carefully lay out.

Let me define a consistent body. Facing right.

Constants (center body line at x=16):
- Head top: y=4
- Cap brim: y=12
- Face bottom/neck: y=18
- Shirt top: y=16
- Belt/overalls top: y=26
- Overalls bottom: y=34
- Hip: y=34
- Knee: y=38
- Ankle: y=42
- Shoe bottom: y=46

Let me draw head (face):
- Face: fillEllipse x=17,y=13, w=13,h=14 (peach)
- Hair: black shape above face under cap. Let me draw hair as a black ellipse slightly overlapping.
- Cap: red dome over head + brim. Cap brim: red rect from x=12,y=11 to x=22 width. Cap dome: red shape.
- Eyes: black. Pupils/eyebrows. Mustache: black rect at y=17.
- Ear? skip.

Torso (constant across walk frames, maybe slight lean):
- Shirt front: red rect x=12,y=16,w=8,h=4 (neck)... 

Hmm let me reconsider with the overalls. Classic: red shirt, blue overalls straps + body. The overalls body sits under the shirt? Actually shirt is tucked into overalls? No—Mario's red is the shirt (collar) and blue overalls are open over the red? Let me recall: Mario's overalls are on top, straps from shoulders, and the blue overalls body covers the red shirt below the straps. The red shirt only shows at the neck/top and sleeves.

So from top: red shirt collar/neck, blue overalls straps going down from shoulders to waist, blue overalls body below straps, then red shirt sleeves on arms, blue overalls legs, brown shoes.

So:
- Neck: red (y 16-18)
- Overalls straps: blue, from neck (y18) down to belt (y26) at sides
- Overalls body: blue, y26 to y34
- Arms: upper arm flesh, then white glove hand; red shirt sleeve between shoulder and glove
- Legs: blue, y34 to y42
- Shoes: brown, y42-46

OK. Let me write.

For arms, I'll draw upper arm (flesh) and glove (white) as segments. The arm hangs down in idle.

Let me just write drawPlayer for frame 0 (idle):

```javascript
function drawPlayer(g, frame) {
    g.fillStyle(0x000000); g.lineStyle(0);
    const SKIN=0xF4C89E, HAI=0x000000, CAP=0xCE1126, SHIRT=0x9B1B2B, BLUE=0x1565C0, GLOVE=0xFFFFFF, SHOE=0x654321;
    
    // Body position offsets per frame
    let armL, armR, legL, legR;
    if (frame===0){ // idle
      armL=[12,24, 12,33]; armR=[20,24,20,33]; legL=[12,34,10,42]; legR=[20,34,22,42];
    } else if(frame===1){ // walk left side up
      armL=[12,22,8,30]; armR=[20,24,24,34]; legL=[12,34,10,42]; legR=[20,34,24,42];
    } else if(frame===2){ // walk right side up
      armL=[12,24,14,34]; armR=[20,22,24,30]; legL=[12,34,14,42]; legR=[20,34,20,42];
    } else { // jump
      armL=[12,22,12,28]; armR=[20,22,20,28]; legL=[12,34,12,42]; legR=[20,34,18,42];
    }
    ...
}
```

Hmm, armL as upper arm line vs lower arm + glove. This is getting complicated. Let me represent each arm as two segments: upper arm (flesh) and forearm (flesh+ glove hand). For idle arms hanging, the elbow is near the hip, glove at ankle-ish.

Actually for simplicity, let me draw arms as: upper arm rect (flesh) from shoulder to elbow, and a glove+hand (white) at the end. For legs: thigh (blue) from hip to knee, shin (blue) from knee to ankle, shoe (brown).

Let me define limb geometry more fully:

Arm (upper): shoulder S, elbow E, then glove at E (hand). Actually arm has upper and lower; hand holds glove. Let me do: upper arm flesh S->E, lower arm flesh E->W (wrist), glove at W.

For a hanging idle arm: S=(shoulder) at (12,23); E (elbow) at (10,32); W (wrist) at (10,40); glove a small square/circle at W in white. That places hand near shoe.

Hmm that overlaps leg. For a blocky Mario, arms at sides don't go that far. Let me make arms shorter: wrist at around y=36, glove square 4x4.

OK I think I'm overanalyzing pixel art. Let me just produce something recognizable and move on; it doesn't need to be perfect. Let me write a reasonably decent drawing.

Let me reduce complexity: draw arms as single segments (upper arm with glove at end), legs as single segments (blue) with shoes. This gives a readable character.

Arm: flesh line/rect from shoulder to a point, with glove (white) at end. Let me make arms 3px thick rects rotated.

Leg: blue rect from hip to ankle, brown shoe at end.

Let me implement limbs as rotated thin rects using save/translate/rotate.

Actually, rotated thin rects look fine. Let me do:

```javascript
function drawLimb(g, color, x1,y1, x2,y2, thick) {
    const dx=x2-x1, dy=y2-y1;
    const len=Math.hypot(dx,dy);
    if (len===0) return;
    const ang=Math.atan2(dy,dx);
    g.save();
    g.translate(x1,y1);
    g.rotate(ang);
    g.fillStyle(color);
    g.fillRect(0, -thick/2, len, thick);
    g.restore();
}
```

Then for the hand/foot I draw a shape at the endpoint.

This is clean. Let me use this.

For the player, facing right. Let me define poses with limb endpoints.

Let me define the torso as a constant upright: red shirt top + blue overalls.

Let me define:

```
Shoulders: left (13, 22), right (19, 22)
Hips: (16, 32)  // center
```

Hmm, let me set shoulder line y=22, belt y=28, hip y=32.

Torso:
- Shirt neck/collar: red, at top. A small red trapezoid/rect: x12-20, y16-18.
- Overalls straps: blue rects from (12,18)->(12,28) left strap and (20,18)->(20,28) right strap (4px wide)
- Overalls body: blue rect x12-20, y28-34 (8 wide)... maybe 6px: x13-19
- Arms attach at shoulders

Let me draw:
```
g.fillStyle(SHIRT); g.fillRect(12,16,8,4); // neck/collar of shirt
g.fillStyle(BLUE); 
  g.fillRect(11,18,4,12); // left strap (x11..15)
  g.fillRect(19,18,4,12); // right strap (x19..23)  -- overlaps body
  g.fillRect(13,28,6,8); // body
```
Wait straps should attach below collar. Left strap at x~11-15, right at x~19-23. Body at x~13-19.

Arms (flesh upper arm, white glove hand):
- left arm: shoulder (11,22) -> elbow -> wrist -> glove
- right arm: shoulder (21,22) -> ...

For idle: arms hang down. Let me make left arm: shoulder (11,22) to wrist (9,36), glove 4x4 white at (6,36)?? That makes arm point down-left. Hmm facing right, left arm is on viewer's... the left side of the screen is the character's right? Wait, if facing right (toward +x), then the character's left hand is on the viewer's right side (screen-right). Let me be careful.

Character faces right (+x direction, toward screen right). So:
- Character's left side = screen right side (higher x)
- Character's right side = screen left side (lower x)

So character's left hand (glove) is on the screen-right. Character's right hand on screen-left.

So:
- Left shoulder (character's left = screen right): x=21, y=22
- Right shoulder (screen left): x=11, y=22

Left arm hangs down on screen-right side; right arm on screen-left.

Idle pose:
- Right arm: shoulder (11,22), wrist (9,35), glove at (6,35) [screen-left side]
- Left arm: shoulder (21,22), wrist (23,35), glove at (23,35) area [screen-right]

Hmm glove should be below wrist. Let me put glove as 4x4 centered near wrist.

This is fine. Let me define left arm endpoints for frames:
- idle: shoulder(21,22) -> elbow(22,30) -> wrist(20,35) -> glove(20,35)
- walk1: shoulder(21,22)->elbow(24,31)->wrist(22,38)->glove
- walk2: shoulder(21,22)->elbow(20,30)->wrist(20,36)

For two-segment arm, I draw upper arm shoulder->elbow and lower elbow->wrist, then glove at wrist.

OK let me just write it with the drawLimb helper and explicit points.

Let me define each frame's limb points. I'll use two-segment arms (upper + forearm) and two-segment legs (thigh + shin) + shoes.

Let me define:

Idle (frame 0):
- RUpper: (11,22)->(10,30)
- RForearm: (10,30)->(9,36), glove at (6,35)
- LUpper: (21,22)->(22,30)
- LForearm: (22,30)->(23,36), glove at (23,35)
- RThigh: (14,28)->(12,36)  [right leg, screen left]
- RShin: (12,36)->(10,42), shoe at (8,42)
- LThigh: (18,28)->(20,36)
- LShin: (20,36)->(22,42), shoe (12,42)

walk1 (frame 1): arms/legs swapped-ish
- RUpper: (11,22)->(9,29)
- RForearm: (9,29)->(11,35), glove (9,35)
- LUpper: (21,22)->(23,29)
- LForearm: (23,29)->(22,35), glove (22,35)
- RThigh: (14,28)->(12,36)
- RShin: (12,36)->(10,42)
- LThigh: (18,28)->(20,36)
- LShin: (20,36)->(24,42)

walk2 (frame 2): opposite
- RUpper: (11,22)->(13,29)
- RForearm: (13,29)->(11,35), glove(11,35)
- LUpper: (21,22)->(19,29)
- LForearm: (19,29)->(20,35), glove(20,35)
- legs accordingly

jump (frame 3): arms up, legs tucked
- RUpper: (11,22)->(10,26)
- RForearm: (10,26)->(12,30), glove(12,30)
- LUpper: (21,22)->(22,26)
- LForearm: (22,26)->(20,30), glove(20,30)
- RThigh:(14,28)->(14,38), RShin:(14,38)->(14,42)
- LThigh:(18,28)->(18,38), LShin:(18,38)->(18,42)

Hmm in jump, arms raised is good. Let me set jump arms to raise upward: RForearm goes up-left. Eh, let me just have arms raised sideways.

This is getting very detailed. Let me just pick reasonable values and code it. The visual quality will be "recognizable Mario-style blob". That's acceptable.

Let me write the code now and iterate. I'll produce the file.

Let me also reconsider: maybe simpler is better — use a 3-frame approach. Let me commit to writing it.

Let me also make the head/face simpler: face oval, hair, cap, eyes, mouth, mustache. For the cap, I'll draw a red dome + brim + a logo-like mark maybe.

OK, let me write the entire index.html now. I'll be thorough.

Let me also plan the enemy (Goomba):
- 32x32
- Brown body (0x8D6A41 or 0xA0522D), rounded rect
- White eyes with black pupils
- No legs (just feet lines) 
- Simple.

Coin:
- Yellow circle 0xD4AF37, 16x16
- Add shine.
- Spin via tween rotation or swap frames. Let me do a continuous rotation tween on the coin and a shine flicker.

Block (brick/brown):
- 32x32 brown 0x8B4513 with darker brick grout lines, or a ? block (yellow with ? mark). Let me make brick blocks and ? blocks (with question mark). I'll make a generic "block" with brick pattern; used as floating platforms and ? to hold coins maybe. Let me make it a brown brick.

Actually let me have:
- 'brick' (brown, breakable - but breaking optional). Let me have brick blocks that are solid.
- '?' block: yellow, with question mark.

Pipe:
- 32 wide, 48 tall? Pipes usually taller. Let me make pipe segment 32x32 green, stack vertically. A pipe is 1 block wide, multiple tall.

Ground:
- 32x32 tile, brownish (0x8B4513 / 0xA0522D). I'll draw a repeating ground tile. But ground tiles repeat as a tileSprite or multiple sprites. Let me draw a ground tile texture 32x32 and place them across the bottom.

Actually, for the ground, I can use a tileSprite or place ground tiles. Let me place a ground tile texture across. To make world bounds and visual, I'll fill ground with tile sprites.

Let me make ground a long rectangle drawn with a tileSprite using a 32x32 ground texture. Similarly background.

Background:
- sky gradient. I'll draw a sky rectangle with gradient? Graphics gradient fill available via `fillGradientStyle`. I can create a large graphics covering the world and fill gradient, then generateTexture... but background should be big. Let me just set scene.backgroundColor to a sky blue and add distant hills/mountains as drawn shapes, plus clouds (procedural). For simplicity, set background color and add a few cloud shapes/tiles and distant mountains.

Let me draw a background using a tileSprite or just large rects. I'll create a 'sky' by setting backgroundColor and then draw mountains and clouds as static graphics at world bounds using a separate tileSprite.

Let me keep background light: sky color rectangles for far buildings, a sun, clouds. I'll generate a 'cloud' texture and place a few, plus a 'mountain' tileSprite.

Hmm, to not overdo, let me:
- background color = sky blue (#5c94fc)
- Add a few large mountain shapes (dark) as a tileSprite with a generated 'mountain' texture spanning
- Add clouds (white puffs) generated texture, placed
- Add a sun (yellow circle) near top-left of world

Let me do mountains as one big generated texture (e.g., 1200x200) drawn with triangles, placed as tileSprite or static image at y bottom. Good enough.

OK let me also think about the camera and parallax for background. I'll make background move at a slower scroll factor for parallax.

Let me now write everything.

Let me write helper for random with seed for reproducibility of level. I'll seed the level deterministically so it's consistent. I'll use a simple seeded random or just a fixed level. Let me use a hand-crafted level for guaranteed quality, plus random coin placement.

Decision: hand-craft the level (platform positions) for quality and solvability. Place enemies and coins procedurally-ish (with seeded RNG) on/for platforms. This balances fun and reliability.

Let me define the level geometry:

World width: 2600. Ground at y=460 (bottom 60px tall). Platforms floating above.

Let me lay out a sequence:

I'll create platforms as a list. Let me define key positions:

1. Start ground: x 0..2600, y 460, thick 60.
2. Floating platform near start: x:140..280 y:400
3. Platform: x:340..480 y:360
4. High platform: x:540..640 y:260
5. Platform down: x:700..840 y:380
6. Moving? skip
7. Pipe at x:760... 
8. Platform chain: x:900..1000 y:420, x:1050..1150 y:360, x:1200..1320 y:300
9. Enemy area
10. Block group with coins
11. Final: flag at x:2400

Let me make it more carefully designed so the jumps are doable. The player runs at speed 250, can jump -550 vel with gravity 1000. Max horizontal run-up to jump.

Let me compute reachable jump: horizontal speed ~250, time to jump apex etc. Actually let me just make gaps ≤ ~150px wide and height differences ≤ ~120px.

Let me design with these constraints.

Let me write the level as an array of platform objects: {x,y,w,h, kind:'ground'|'float'|'block'}.

I'll also place enemies at certain x on platforms, coins along paths.

This is a fair amount. Let me write it.

Actually, since I can't easily see results while writing (well, I could run a quick server, but it's a browser game needing display; I can at least check for JS errors via a headless-ish check). Let me be careful to avoid runtime errors.

Let me write the code and then test by loading in a headless browser if available (maybe node can't render Phaser). I'll at least check syntax with node --check or a browser check.

Phaser requires DOM/canvas. Running headless might fail. But I can at least do a JS syntax check by extracting the script. Let me try to verify the script syntax with node after creating.

Hmm, node won't load phaser (needs DOM). But I can syntax-check the script content with `node --check`. Let me do that.

Let me also consider: to test rendering, maybe there's no display. I'll rely on careful code.

Let me write the full file now.

Let me carefully write the graphics generation using Phaser graphics and generateTexture.

One concern: `generateTexture` for a Graphics — the proper usage is:
```
let rt = this.add.existing(this.add.graphics());
rt.generateTexture('key', w, h);
```
or `this.add.graphics().generateTexture('key', w, h)`. Actually `generateTexture` is a method that renders the existing Game Object into a texture. But the graphics object must be in the scene and have been rendered. There's a known technique: create a Graphics object, call `generateTexture(key, width, height)`.

Wait, I recall `generateTexture` is defined on GameObjects (via the Texture method? Actually it's on GameObject: `gameObject.generateTexture(key, width, height)`)? Let me verify. In Phaser 3, `Phaser.GameObjects.GameObject` has methods... Actually the method to capture a GameObject to a texture is:
- For a single GameObject, use `this.add.renderTexture(...)` or `this.make.bitmapData`?
- There's `GameObject.generateTexture`? Hmm.

Actually, the well-known approach is using `this.add.graphics().generateTexture('key', w, h)`. Let me confirm: Phaser's `Image` and others... There is `Phaser.GameObjects.Components.Texture`? 

Let me recall concrete examples: 
```
let graphics = this.add.graphics({ x: 0, y: 0 });
graphics.fillStyle(0xff0000);
graphics.fillRect(0, 0, 100, 100);
graphics.generateTexture('red', 100, 100);
```
Yes, I'm fairly confident `generateTexture` exists on Graphics/GameObjects to create a texture from current content. This is a documented pattern. Good.

Actually wait — `generateTexture` is a method of `RenderTexture`? No. Let me recall: The method is on the GameObject base class? I believe Phaser.GameObjects.GameObject does NOT have generateTexture. But Graphics does via `Phaser.GameObjects.Graphics.generateTexture`? 

Let me verify via the file. I'll grep phaser.min.js for generateTexture.

Let me check.

I'll run a grep.

Phaser 3.80.1 is confirmed. Let me verify a couple of API details (the `generateTexture` method and graphics methods I'll use) before writing the game.

Good. So `generateTexture:function(t,e,i)` - takes key, width, height. And `fillEllipse`, `strokeEllipse`, `fillGradientStyle`, `fillCircle`, `fillRect`, `lineStyle`, etc are available.

Let me verify the Graphics methods: `fillEllipse`, `fillCircle`, `fillRect`, `strokeEllipse`, `fillGradientStyle`, `lineStyle`, `save`/`restore`. Let me check save/restore on graphics.

The grep showed `restore()` 31 times and `save` - let me verify graphics has save/restore.
