Aaaaaaaarrrrrggghhhhh, that's all I can say.....you start getting into a rythm and think it's easy, then BLAMMo, faaaaaaaaake! Of all the submissions I've played and rated so far, this is the only one that's honestly had some real replayability. I think you could build on this, add different colours/shapes with perhaps some kind of bonus multiplier attached to them. Add a little more polish and you've got yourself a great mobile game here, well done.
