A puzzle game, designed to teach the player Newtonian physics through gameplay.
Why am I talking about it?
Because it sounds to me like a good idea and a good cause, I know some of the folks involved with the project, and the Kickstarter campaign just launched.
Is it good?
Well, I hope so! And since even a one-dollar donation gets you a copy of the game, I have every intention of finding out for myself. XD (But more seriously, they've tried the old version in classrooms, and it seemed to help.)
