8bit-Grubs is an artillery style Tech Demo introduced in release 0.2.0 (of 8bit-Unity). The code shows how to use sprites and get/set pixel color on bitmaps.
8bit-Unity is the only cross-platform C language SDK for 8bit computers, which allows writing your game just once, and then deploy it on all those platforms! Furthermore, the integrated asset pipeline makes it super easy to produce bitmaps, sprites, and music for your game!
