Great game! I especially like the creativity in different block types, which makes it much better than typical "Drop Box" based game.
The main issue is that this game seems to be designed specifically for iOS. Not that there's anything wrong with that per se, but there are levels where multitouch would make things way easier, while completing it with mouse is much more difficult. So far I've managed to get quite far, but currently I'm stuck on level 30 where multitouch is *necessary* to complete this.
I don't know, maybe replace these multitouch-oriented levels with some other puzzles, so PC players will be able to complete that, too? O.o
