**Planning game development** I need to create an index.html file, inspecting the current working directory. It's important to write everything in full and make the canvas polished without any external dependencies. I'll implement game controls using the arrow keys, WASD for movement, and buttons for jumping and restarting. The game needs to be playable, so I'm thinking of crafting a robust JavaScript canvas that is responsive with tiles in a grid of 80 columns and 20 rows. I need to consider camera placement, platforms, hazards, enemies, and maybe a trophy exit that's locked until a trophy is collected. Additionally, I’ll focus on physics, collision detection, procedural graphics, and a user interface to ensure smooth keyboard functionality. It looks like I have a lot of writing to do!

EVALUATION
Platformer level with spikes, fire, water, and enemy renders nicely, but player sprite never moves despite inputs.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
