I've made this simple paint, it's not a great painting program, just a funny thing. LINK TO THE GAME
What differences this one from all the other paints around the internet is that this one has the physics option. Turning it on will make all your painting get the physics behavior.
Chosing the size of the brush won't set the painting you will do to the size you chose, it will set the one already done.
Any tips or ideas, please post :D
