Prequel
primitive recursive driven programming
This 2D-polygon game engine sets up a makerspace where programmers can share their rich expressions, despite (perhaps thanks to) the intentionally limited resources provided.
Prototype ideas using only uniformly colored convex polygons.
Create and run code external to the main program.
Useful for example to let people create bots without changing (and even without looking at) the main program.
No registry, no cookies, no ads, no tracking.
Enjoy!

Try the examples and have a look at their source code () to see what makes them tick.
