You play with crayons and physics. The goal of the game is to move the red ball so that it collects the stars. You can cause the red ball to move by drawing physical objects.

Changes:

New rendering engine using OpenGL, a lot more faster than the previous one and with texture support!
Support for images and animations for objects, as can be seen on the first level of the Crayon Physics pack (I’ll update the others in the next update)
Sound effects, and an option on the main menu to turn them off. The sound is currently playing as a system sound, so you have to turn them on to hear anything.
Multi-touch support! Up to 5 simultaneous touches are registered and processed. For now it’s only useful for triggers, but I may add something extra for them in the future.
Basic scoring added, online scoring soon to come.
Some new flags and trigger actions, see the iPhysics_Levelpack_Format page.
