GreenGoat,
I've been playing and rating all of the games and yours stands out as an absolute gem. It's a spectacular idea for the theme, the controls are snappy, intuitive, and have great sound effects. Music fits the game. Puzzles are well thought out and steadily increase in difficulty. Art is simple and extremely effective. Introducing the pass-through walls by simply telling us how to restart is clever.
You will receive a great rating from me!
(If you're looking for constructive feedback, the level pictured in this page's third screenshot was difficult for me because the brick pattern makes it a bit difficult to picture each separate tile. Otherwise, impressive work. I love you)
