Nice concept. Very hard to do since both the players must draw with the same mouse. Kinda strange moving around, and the jumping pokes my eardrums a little lol. The drawing/orb thingies could use a a slight cooldown, maybe.

This game is nice concept wise, but has a few important kinks to iron out. The parallax scrolling should be toned down because it really hurts your eyes, camera should be pulled farther back to actually get to see your stars, and a pointer to know where the stars actually are wouldn't hurt.
