It renders fine. I should sanity-check the movement and level reachability by briefly simulating holding right and jumping.

thinking
I can't fully verify playability from here, but doing a quick sanity check: the first jump reaches about 3 tiles high given the gravity value, which seems reasonable for the platform spacing in this level. So the water pit is actually sealed beneath solid bricks and unreachable, just decorative. The fire pit further along is genuinely open though, five tiles wide, too far to jump directly, but there's an upper platform route around it via the row above that lets me bypass the hazard safely.
The game is written to `/tmp/job-fb3VR9/index.html`. I haven't played it through to the exit. What I checked in the browser: - **Rendering:** the level draws correctly. I can see brick tiles, fire, water, gems, a trophy, a magenta enemy and the player. - **Enemy:** it patrols back and forth on its platform. - **Console:** nothing worrying. The only message is a generic sandbox iframe warning. - **Not tested:** my single key tap was too brief to move the player. I haven't tested jumping, collecting the trophy, hazard deaths or the exit door. The level looks completable from the layout, but I haven't confirmed it. The first jump is about 3 tiles high. The water in the middle of the level is under solid bricks, so it can't be reached and is only decoration there. The fire pit and the water at the far right are reachable hazards. **Controls:** Arrow keys or WASD move, Up, W or Space jump, and R restarts. **Rules:** you start with 3 lives. Fire, water, weeds, enemies and falling off the map each cost a life. You have to pick up the trophy before the door lets you finish.
