Algodoo

This is a simple, actually trivial game, involving some colorful dots. The goal of the game is to, by using arrow keys, make the number on the green box bigger, that's your score.
This is what the world looks like to a neural network. All the neural network can see is the direct values you hand it, no more, no less. Try the game out for a while, you might actually learn how to play, just like the neural network. But in either case, neither you nor it will ever truly understand what you're doing, just that what you are doing is encouraged behavior. If you still need more help than the neural network does, press W to reveal what each dot means, and press S to hide it.

This game is a concept I had since I first ever learned scripting was a thing in Algodoo, and while I had phunlets that kind of did this, none were this beautiful or accurate.
