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.

The game is now playable in the browser. The player can move left and right using the arrow keys or A and D keys, and jump using the space bar. The goal is to collect the trophy and reach the exit without touching the enemy or hazards. If the player reaches the exit without the trophy, they will get a "Game Over" message. If they collect the trophy and reach the exit, they will get a "You Won!" message. The player can restart the game by pressing the R key.
