Hi everyone, I have been thinking of improving one of my games named Colorise. So far I have decided that I want to add a multiplayer mode, change a few things and fix some bugs but I can't think of any new mechanics besides adding spikes and obstacles, but I would prefer doing something different. Also, since I'm mostly a programmer I really would like some suggestions on the art of the game too.
