Amazing game! The music is nice, the gameplay is smooth, and the concept is great. It's super enjoyable and the feed back when setting the tile is very satisfying. Can't believe I did worst the second time ^^
I agree with some comments below, the randomization could be a little bit improved, such as making the shape list shuffle at the beginning of the level and then let the shapes follow the list from topp to bottom, or something like that.
Anyway, congratulation for this entry!
