This game had a really nice concept!
The story was fun, but I did have an issue where in my first playthrough, I died to zombies and in my second and third I couldn't see any zombies at all. After redownloading it worked.
Instructions on how to hit the zombies would also be nice! I also couldn't find the exit game button so I had to manually end the task.
Overall though, this was a fun concept! Keep it up!
