Draw shapes and use the laws of physics to reach the target. Make clever use of physic to collect all flags in each level. The shapes that you draw are affected by gravity, friction and inertia. Use these properties in your advantage. The red ball (or red square in some levels), is the object...

You have to place an atom somewhere, and the red dots are gravity sources.Try not to hit the gravity sources before the red bar on the bottom runs out!
