About Bitty Engine

Bitty Engine is a cross-platform itty bitty Game Engine and open-source Framework. The full featured engine is programmable in Lua and integrated with built-in editors. It keeps the nature of both engine's productivity, and fantasy computer/console's ease to iterate. It boosts your commercial/non-commercial projects, prototypes, game jams, or just thought experiments.
It is supposed to be your ultimate 2D game creating software.

Bitty Engine offers a set of orthogonal features that makes game development comfortable and enjoyable.

These features are quite stable. Things just change, but it is very important that there won't be unthoughtful breaking changes in future development.
