All around awesome!
Great game! Awesome gameplay, sick mechanics, and beautiful graphics/music. everything fits togethor so well!
my only complaint is that it doesn't get any harder, and it gets really easy really quick. I dig that it's all random, but maybe somehow increase the spawning points for the pushies and decrease the spawns of + and S after every 5000 or so.
kudos on a great game! (btw, 25483 on insane, and I only quit because it got boring ;)
