doukutsu-rs initially started as a Rust learning project, but eventually evolved into semi-playable and compatible reimplementation of the engine of Cave Story - a great indie game created by Studio Pixel.

The project aims to deliver a decent alternative for the original engine, improving it with features such as multiplayer support, powerful Lua API (no more unportable ASM-hack based mods), and independent framerate (so the game runs at original speed and looks smooth regardless of monitor refresh rate).
