Fun enough game, however the game over screen makes it seem like a complaint rather than a serious attempt at a game. Also, the upgrade system wasn't complex enough.
The zombies become hard to see after a while due to the blood. I'm not sure what day I'm on either. I can no longer gather survivors, and they were the only truly effective way of gaining experience.
After playing for a good half hour, I decided it's time to do more important work. It is unfortunate that I will be unable to return to my progress afterwards though.
The ai is pretty bad. I had a double jump lined up but couldn't do it, while the computer proceeded to double jump me the next turn because of my piece's poor position.
