Did someone say Pinball??

Well, are you going to tell him how, or just tease him???
I would tell him how, but I used basic methods (as above) for my Pinball WIP. (setting bumpers to a circle shape of course, not square)
I would love to see more Virtual Pinball Machines made with AppGameKit!
As well as other retro non-electrical and mechanical electronic games, like the one he is working on.
It looks like those little boxes that had a ball in it and you had to roll through the maze avoiding all of the traps (holes) to win.
Gyroscope and a steady hand would come into play here.
