Extremely fun and rewarding, as well as incredibly unique! I very much enjoyed this puzzle game and wish there were others like it! Much to my shame, however, I gave up after level 50 :P After that point it became less about skill and more of a guessing game as to what shape the creature was thinking of when they made it, seeing as how, realistically, MANY items could fit into the boundaries stated. Other than that though, just stupendous!
