Enjoyable
A very good and fun puzzle game, with such a deceptively simple idea - took me a while, but I did complete it!
The graphics could probably do with a bit of a tweak - whilst they looked good in a simplistic way, they weren't that interesting to look at after a while. A few subtle 3D effects and possibly a slight glassy effect on the blocks could really make this game stand out even more.
But on the whole, a very fun little game.
