Prompt for this run
Build a playable tile-based platformer on a canvas in a Dangerous Dave-inspired style. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Provide one completable level with solid platforms, a trophy, an exit, fire and water hazards, and at least one patrolling enemy. Draw everything procedurally. - Use Left/Right or A/D to move and Space to jump. Display the controls. Apply gravity, landing, and solid-wall collision; jumping is allowed only while grounded. - The player must collect the trophy before the exit completes the level. Reaching the exit without it gives visible feedback and keeps the level active. - Touching a hazard or enemy causes a loss state. Reaching the exit with the trophy causes a win state. - Provide Restart after either outcome and during play. Restart restores the level, trophy, enemies, and player position. Keep the level's route physically reachable. Verify: Test movement and a jump near the starting area. Check that the player lands on a nearby solid surface and that the trophy and exit are visibly identifiable. Use Restart and check that the initial player and collectible state return.

Built `index.html` — a self-contained, canvas-based Dangerous Dave-style tile platformer (no external assets/CDNs). **Game features:** - 30×20 tile level with solid brick ground/platforms/walls, procedural drawing for player (red-cap Dave), purple patrolling monster, trophy, exit door, animated fire and water hazards, hills/clouds background. - Controls displayed on page: `◀ ▶`/`A D` move, `Space` jump, `R`/Restart button — gravity, grounded-only jump, X/Y solid-wall & landing collision. - Reachable stair route: ground → platforms at rows 15→13→11→9 (trophy) →7 (exit), each step 2–3 tiles up with ≤2-tile gaps (jump height ~139px verified). - Exit without trophy: shows “🔒 Locked! You need the TROPHY first!” in status bar and “NEED TROPHY!” above door, level stays active. Exit with trophy → win overlay. Fire/water/enemy contact → loss overlay. Restart (button/`R`/`Enter`) resets player, trophy, enemy, and state. **Actually checked:** - Browser inspect/screenshot: console empty, player visibly landed on ground at left spawn, purple enemy, fire, water pits, golden “TROPHY” and “EXIT 🔒” door clearly identifiable, controls/legend/Restart button rendered. - Node logic harness (stubbed canvas, ran real game code): settling lands at y=548 on ground; holding Right moves +102px/30 frames; jump in open area gains 139px and lands back; Left wall stops at x=32; trophy pickup sets `hasTrophy`, exit without it stays `playing`, exit with it → `won`; fire → `lost`, enemy → `lost`; reset restores spawn (68,548), `hasTrophy=false`, `playing`. - Browser Restart-button click re-inspected: initial state/status restored. **Remaining unverified:** Full human playthrough from spawn to trophy to exit via keyboard in the browser tool (single key taps don’t hold long enough to traverse platforms), and water-hazard death in-browser (verified logically via same hazard code path as fire, but not visually triggered).
