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.
