For 2025's Bunkasai I created Heyuri in the Realm of the Mad Fuck (fresh OC pic related) with Godot. Booting up the game and listening to the music you guys suggested warms my heart btw.

Because I'm a nostalgic I wished for a self-contained game engine that could be deployed in a single file in the style of Flash games, I created a simple game engine that packs everything inside an HTML file you can run anywhere.

I will be preparing to travel to Japan during Bunkasai this year, so I might not be able to contribute, so I'm posting this now.

Included is sample code and documentation for the engine. I hope this is useful for someone. If not, I might still be able to cook up something for this year's Bunkasai.
