Brilliant optical game. Just a couple ideas: 1. The player can sometimes become white, meaning they can pass through anything. Also, color-blind mode would be nice (I'm not colorblind myself, but still).
Because of the predominant strategy (do not divide, just conquer), I think in MK2, divisions should be automatic as soon as the player reaches a certain size threshold. More levels and a storyline would be greatly appreciated, but for now, I'll give you 4/5.
Listen, buddy. If people think games make turds look like gold, then they'll rate 'em 1/5. That's the way it is here. It's better than Newgrounds here, though: poorly rated games just don't show up except on your page (I think), they aren't deleted. But if you're afraid of your game getting negative feedback, don't post it. P.S.: I rated 1/5, because a) this game does suck, and b) I like proving points.
