Game update is started!

Hello everyone! I started to make an update for my game. It is not a global update, but it still very big. Now i finished upgrading the shop. Also i added more zombies: zombies now die from one hit and the number of zombies on the screen increases every second! Now you can earn a lot of money so i increased the price of all upgrades in the shop. This is all for this day. Keep for more updates!
