Okay, as promised, I reviewed this game too! As I was on a Mac, it was a bit painfuly slow (not going to take you points away for that; its not a game intended for Mac) and the right click didnt work, for a lack of a mouse. So I wasn't able to finish the last two levels. Even though I had this issue, I can see that the game felt very polished; grabbing the cubes was really nice and way less clunky than when I tried to design something similar. The game idea was nice, too (the first labyrinth level in particular). A quite unique interpretation of the theme.
Good job :)
