This is a prototype for an engine suggestion I made for Padra4's RBNRA game. Its purpose is to show how to lay out the Prime Factor framework more efficiently than what is currently there. It is in the form of a single sprite with a few automatically generated lists, so you could paste it into a project and it should work without additional setup.
Just about everything by me (Padra4 gets credit for spurring me to make this ig) Note: I currently haven't gotten to displaying the Prime Factor amounts but that can easily be fixed with a text engine
