Usagi Engine

Usagi is a 2D game engine for making pixel art games in Lua 5.5. It features live reload, single-command cross-platform export, and a pause menu with input remapping built in.

Features:

• Live reload. "usagi dev" watches your code and assets; saves apply without losing game state. Tweak a sprite in your editor and see it update instantly.
• One-command export. "usagi export" packages your game for Linux, macOS, Windows, and the web.
• Pause menu, free. Built-in pause menu with sfx and music volume, fullscreen toggle, and per-game keyboard + gamepad remapping.
• Easy save data. One function to save and load your game state as a Lua table.
• Small, fixed API. You can't do everything, but you've got what you need to make a great 2D game.
• Constraints to inspire creativity. 320x180 default resolution, 16x16 default sprite grid, a single "sprites.png" for textures.

Bring your own sound effects, sprite editor, and music tools.
