kristjan-jonsson/walk-the-line — reverse-engineered prompt

Build me a simple browser playable game called Walk the Line. It should feel like a minimalist endless platformer where the whole world is one chalk line. The player controls a small chalk style character who can walk left and right, sprint, jump, restart, mute music, and quit on desktop.

The goal is to keep moving along the line, jump over gaps and obstacles, avoid enemies or walls, and see how far you can get. Please include basic scoring or distance tracking, a high score saved locally, sound or music with mute, simple sprites and level assets, and a few level configs so it’s not the same run every time.

Make it work locally as a Python pygame project, and also make it build for the web with pygbag so I can publish it on GitHub Pages. Add a clean README with controls, setup, browser build steps, and deployment notes. Look up current docs online if you need to.
