About
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.
Problem
Developers who want to quickly prototype 2D pixel art games lack a simple, opinionated engine that avoids the complexity of tools like Love2D while exceeding the limits of fantasy consoles like Pico-8.
For
indie game developers and game programming beginners looking for a simple 2D prototyping environment
How it works
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.
