Usagi 2D Game Engine

Usagi is a newly surfaced free and open-source 2D game engine that targets Windows, Mac, and Linux, with Lua as its scripting language. The article frames it as an easy-to-use option and explicitly calls out inspiration from LÖVE and PICO-8, which gives a pretty clear signal about the intended workflow and scope.

For developers, the main appeal is the combination of cross-platform support, open source access, and a lightweight Lua-centric approach. That makes it potentially interesting for rapid prototyping, jam projects, and smaller 2D games where you want less engine overhead and more direct control. The post doesn’t go deep on technical specs, so the practical takeaway is mostly about positioning: another entry in the minimalist 2D engine space, with enough familiarity to be approachable but enough openness to be worth a look.
