This was really fun! A great zombies game with all the mechanics you want like upgrades, a shotgun and a good melee option. The how to play section was really cool and easy to understand too. I couldn't seem to get the heath buying and upgrades to work, or rather if they did I couldn't tell (maybe like a cash register sound to register it happened for future updates?). But definitely had a lot of fun with this one! My favorite strategy was stabbing zombies from inside before they broke through the wall. Great job!
