Each stage in Crayon Physics Deluxe features at least two objects: a ball and one or more stars. Your goal is to move the ball to collect the stars and finish the stage. It's that simple. Using the left mouse button you can draw using crayon-style lines. Click, drag, and when you release, the shape you made comes alive and is given mass. You can draw wild shapes, plain shapes, lines, hearts, stars, bacon, monkeys, and everything in-between, it all interacts using realistic physics. You can even build rudimentary machines that are powered by gravity, attach shapes using hinges, and give the ball a little boost by clicking on it. Don't let typical gaming conventions limit yourself, as creativity is the key to enjoying Crayon Physics Deluxe.
