I like the idea of manually moving your zombies around to solve puzzles. One thing that I wanted was to be able to control multiple zombies at one time. The zombies are also quite slow so killing a guard far away from where you want that zombie to move to, you'll have time for a short nap haha. Waiting for one zombie to reach his destination before being allowed to move another zombie made me cry.
Nice work though, the puzzles were neat and I liked the concept!
