Great polished game, it's really challenging! I love the art, this is an excellent clean style. A lot of content for just one week. Your music choice is very good. It has a lot of potential for being a success as a android/iOS puzzle game, reminds me a bit of cut the rope.
It would be cool if you get squashed by moving tiles rather than falling through all tiles. One thing I noticed is that the difficulty of some levels are not in order, f.e. 2-4 is much easier than 2-3, but thats just my opinion. Enjoyed it!
