Shroom of Radiance is an attempt to write all of the code for a dungeon crawler and tactical combat system with Claude Sonnet 4.5 within 9 days. All code written was 100% generated by AI, even the little bits like "move the title down 4px".  The project is a react-app written in TypeScript and rendered almost entirely on an HTML canvas.

This is the result! With 60,000 lines of code, this monstrosity is now published.

I will hopefully add more text to this in the future. But for now, I must sleep.
