Build a playable Tetris on a canvas with all seven tetrominoes, rotation, line clears, increasing speed, a next-piece preview, and score.
thinking
The user wants me to build a complete Tetris game in a single HTML file with:
- Canvas-based rendering
- All seven tetrominoes (I, O, T, S, Z, J, L)
- Rotation
- Line clears
- Increasing speed
- Next piece preview
- Score
I'll create a self-contained HTML file with CSS in a `<style>` tag and JavaScript in a `<script>` tag. No external resources.
Let me write this out:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Tetris</title>
<style>
/* CSS styles */
</style>
</head>
<body>
<div class="game-container">
<canvas id="game-canvas" width="240" height="400"></canvas>
<div class="info-panel">
<div>Next:</div>
<canvas id="next-canvas" width="80" height="80"></canvas>
<div>Score: <span id="score">0</span></div>
<div>Level: <span id="level">1</span></div>
<div>Lines: <span id="lines">0</span></div>
</div>
</div>
<style>
/* ... */
</style>
<script>

</script>
</body>
</html>

The file was created successfully. Let me provide a summary of what's in the file.
Created `index.html` with a complete Tetris game featuring: **Features:** - **All 7 tetrominoes** (I, O, T, S, Z, J, L) with distinctive colors - **Rotation** using Arrow Up or P key - **Line clears** with scoring (100/300/500/800 points based on 1/2/3/4 lines) - **Increasing speed** - level increases every 10 lines, drop speed accelerates - **Next piece preview** showing what's coming - **Ghost piece** showing where the piece will land - **Score, level, and lines tracking** - **Hard drop** (Space) and soft drop (Down arrow) - **Pause** functionality (P key) - **Game over detection** with restart option **Controls:** - `←` `→` : Move left/right - `↑` : Rotate - `↓` : Soft drop (+1 point) - `Space` : Hard drop (+2 points per cell) - `P` : Pause The game uses a dark theme with glowing effects and gradient blocks. No external dependencies - runs entirely in the browser.

RUN
EVALUATION
Functional Tetris with falling pieces, next preview, score/level/lines, responds to keyboard input by placing pieces and scoring.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
