**Creating index file**

I’m thinking about creating an index.html. It's essential to check the current working directory (cwd) first to ensure everything is organized. I want to make sure that I’m starting off on the right path. I’ll consider how to structure the HTML and determine any necessary elements to include, like the head and body sections. Let's ensure it’s set up properly from the get-go!
bash {"command":"pwd && ls -la && echo '--- env ---' && env | grep '^PI_' || true"}

**Planning game development**

I’m thinking about creating index.html and ensuring it looks polished. I might not need to inspect it closely, but I want to write comprehensively. I need to make sure the game is playable with both keyboard and touch controls. The canvas will be 960x540, designed with tiles and a camera. I want to implement procedural visuals, but without directly copying Dangerous Dave. I'll craft a single file, including UI elements, game mechanics, and a coherent level design. Let’s get started!

EVALUATION

1/5 broken

Stuck on the start menu screen; no input (click, keys, drag) starts the game, only text selection changes.

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.
