**Figuring out project setup**

I’m trying to figure out how to set up the project correctly. I think I need to create something, possibly inspect the directory. Maybe it’s just related to Phaser, which would simplify things a bit. I wonder if there's a specific order I should follow. It's all a bit unclear at the moment, but if I can just focus on inspecting the directory, that might help me get moving in the right direction!
bash {"command":"ls -la && printf '\\nPhaser file:\\n' && ls -lh phaser.min.js"}

**Exploring game development requirements**

I want to ensure the game is responsive and scales well, especially for mobile users. This includes considerations for touch inputs, like buttons, and handling pointer events without a network connection. I'm thinking about using deterministic sky textures, although gradients might be tricky with Phaser-generated graphics. Using an HTML background could be a good solution. Let’s get creative and start piecing this all together!

EVALUATION

2/5 partial

Menu screen loads with parallax background, but Enter+Space just dismisses the modal; arrows/WASD show no player movement, drag only selects text.

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.
