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 the playable Dangerous Dave-inspired tile platformer in a single self-contained `index.html` (19 KB, no external assets, CDNs, or network requests). **Features implemented:** - One completable canvas level with solid brick platforms, a high-ledge golden **trophy**, a labeled green **EXIT** door, animated **fire** and **water** hazards, gems, and a purple patrolling monster — all drawn procedurally - Controls displayed on-screen: ←/→ or A/D to move, Space to jump (grounded-only), R to restart - Gravity, landing, and axis-separated solid wall/floor collision - Trophy-gated exit: touching the door without the trophy shows a "🔒 NEED TROPHY!" / "EXIT LOCKED" message, shakes the screen, and keeps the level active - Touching fire, water, or the enemy triggers a Game Over state; reaching the exit with the trophy triggers a Level Complete state - Restart button (and R key) available during play and after either outcome, restoring player position, trophy, gems, and enemy **Verified in the browser:** - Initial render — player landed and standing on the solid ground at the start; trophy (labeled, gold) and EXIT door (labeled, locked icon) are clearly identifiable, as are fire, water, and the enemy - Pressed movement and Space near the start; the player jumped and landed back on the solid starting surface, and the enemy was seen patrolling its platform - Clicked **Restart** after play: player returned to spawn, the monster returned to its start position, the trophy reappeared, and the HUD reset to "Trophy: NOT YET / Status: Playing" - No console errors **Not verified:** a full end-to-end run collecting the trophy and finishing (or deliberately dying) wasn't completed within the session — jump heights/gaps were sized conservatively (max climb ~4 tiles vs. the ≤3-tile steps on the route) so the path is reachable, but win/lose overlays rely on code review rather than a completed playthrough.
