I like the switching colours thing very cool. The art is cute and surroundings are kinda plain. When I played it I killed a bunch of dudes and found a tv and nothing happened. I think I went everywhere, in a different playthrough I left the coloured area and was walking around the gray (opens when I enter room with baddies) and nothing around. So for the next playthrough (the one I found tv) I stayed on the coloured place and I'm pretty sure I went to all the rooms that were possible and I think I killed all the guys. Unless I'm blind and missed an area I can't find a boss. But I think game a mechanics are very cool. Bulb dude is cute
