Usagi Engine
Free, open-source 2D game engine for rapid pixel art prototyping

Usagi Engine is a free, open-source 2D game engine for making pixel art games using Lua 5.5. It features live code and asset reloading during development, single-command cross-platform export (Linux, macOS, Windows, web), and a built-in pause menu with input remapping. The engine is designed for rapid prototyping with intentional constraints like a fixed 320x180 resolution and a small, focused API.
Developers write Lua scripts following a small fixed API, run usagi dev for live-reloading development, and use usagi export to package games for all major platforms in a single command.
