I have just open sourced my 2D game library called Tiny2D.
My focus with this library was on being easy and quick to use. Minimum code, maximum effect. Whether you plan to develop commercial game or just taking part in some game jam, you might be interested.
Current feature set includes:
- animated sprites
- particle effects
- shader based materials
- render targets
- some built-in postprocessing filters
- asynchronous resource loading

Any feedback welcome!
