For collisions I can say p5.play has been an excellent plugin for p5 to handle inertial physics and collisions. I would suggest that the novice game developer might enjoy rolling their own basic collision detection ( object overlay, mouse-over, inertia-ignoring collision resolution, etc), but obviously that is not fun or convenient for everyone. https://p5play.org/learn/ https://p5play.org/learn/ (AGPL licensed with commercial exceptions available these days, it seems)
