RetroBlit: A Retro Pixel Game Framework for Unity

RetroBlit is a retro pixel game framework that aims to create an ideal, low friction framework for making pixel-perfect retro games from the early 90s era. It takes advantage of Unity's portability and ease of deployment, but does away with the Unity Editor interface in favor of a traditional game loop, immediate-mode, and code-only development. This allows for a more traditional game development experience.

Features:

• Pixel perfect rendering

• Primitive shape rendering, lines, rectangles, triangles, ellipses, pixels

• Textured line rendering

• Multi-layered tilemaps with extensive TMX file support

• Rendering to and from sprite sheets

• Rendering raw pixel buffers

• Unicode text rendering, with text alignment, overflow settings, and custom pixel font support

• Sprite packing support

• A set of 30 tweening/interpolation functions

• Clipping

• Custom shader support
