This one is a puzzle game based on the science of physics and the twist is that to move objects, you have to draw them. So you get to solve problems and be creative at the same time. The idea is to make the red ball hit the yellow star, and you draw shapes that will make the red ball move most efficiently.
There are loads of levels to pass through and from my first quick glance it looks like users can also make their own levels too.
