Crayon Physics

Crayon Physics is a freeware puzzle game designed by Petri Purho and released on June 1, 2007. Its object is to guide a ball to a goal point marked by a star or, in the final level, multiple stars. The player does not have direct control over the ball, but can interact with it by drawing shapes with the mouse (e.g., ramps to allow the ball to roll from one platform to another). In this way it is both reminiscent of puzzle games like Marble Madness and Super Monkey Ball and adventure games such as Okami and Magic Pengel.
