I really enjoyed the game. The graphics are nicely done and the puzzles are straightforward while still being a fun brain exercise. I have two things I would like to point out, however. Your stage extends past your game on the right just by a little bit. I was able to get through some of the levels just by bonking zombies into that "limbo" zone with wooden objects. Second, it would be rewarding to have some kind of ending image/sequence to show that we won the game. Your playerbase will enjoy that more than just returning to the level selection screen. All in all, great game!
