this is a great game

Great game with well balanced difficulty. You can go back to a level later if you can't solve it. The levels are well made and a few really made me think. The number of levels makes the game just the right length. The music is a good fit too. On top of all that it has achievements. I think I spotted a bug: When I completed one of the zones it said I had unlocked a challenge, but every challenge was already unlocked. (Rating: 9.5/10)
