Usagi is a 2D Lua game engine built in Rust that enables rapid prototyping with live code and asset reload, cross-platform export, and a built-in pause menu with input remapping. It targets pixel-art game developers seeking a simpler alternative to Love2D or Pico-8, offering a constrained but focused API. The project stands out for combining live reload with a dedicated CLI toolchain and public-domain licensing.

Target audience: game developers, indie game devs, hobbyist programmers
