Having a framerate of 12 is a horrible idea for a drawing game. Make it around 50 or so and make it so that the changing of colors doesn't clear the canvas.
Graphics are horrible, and there are many bugs. You say this is a demo, if you read the uploading terms, it states to not upload demo's to kongregate. Flagged for being a demo, although, I do hope that you get better graphics and go along with this idea.
Oh yes, and the fact everything is credited to a site that Benjackal doesn't have for his own site, and knowing that Benjackal has stolen before, I can only confirm that this game is stolen, please prove that this game is not stolen by contacting me through the exact email address credited in this game or I will only be able to assume it is stolen.
