The game is still under development at the moment, but you can see the demo video here.
It ‘s a very fun game, where you need to draw lines, circles, squares (freehand mode) to make the "ball" moves to collect the star.
Check out the video and you can also play the Crayon Physics Basic edition (the prequel) to test out the game engine.
Check out the Crayon Physics Deluxe site for more and also to register your email address if you want to be notified when the game is out! (I have put mine in ^^)
You can also download the Crayon Physics Basic edition on the site here (Download the zip file, extract the files, and just double click the crayon.exe file. No installation is needed. Have fun!)
