doukutsu-rs

A re-implementation of Cave Story (Doukutsu Monogatari) engine written in Rust, aiming for accuracy and cleaner code. Later plans might involve turning it into a fully-featured modding tool with live debugging and stuff.

The project is still in a very early state and nowhere near being playable. Expect lots of breaking changes and bugs

Data files

doukutsu-rs project does not re-distribute any copyrighted files.

The engine should work fine with CSE2 or NXEngine modified freeware data files and Cave Story+ (Nicalis commercial release, loading is supported but note we're not aiming to fully support it's features) data files.

Roadmap

• Tilemap and player rendering
• Weapons
• Text scripts (TSC)
• Making it actually playable
• Modding enhancements and built-in tools
• idk the list is TBD

why rust, it's a hipster language lol

The project is a result of me wanting to build something in a new programming language for memes.

I had an idea of writing my own CS engine long time before and I would've very likely picked C++17/20+SDL2, but after all I've picked Rust instead because it seemed quite interesting for me.

Would 90% of end-users running this thing care about the programming language software was written in? After all who tf cares if the performance is the same (and maybe a slightly better), but you also get a lot of various benefits?
