[Android][Free]Zombie Defender - A wave based defender game Thread

Hey,
i´m Nicklas from Polywog games and Zombie Defender is our first game that we released.
The game is about defending yourself against massive zombie waves. Your weapon is a small crossbow, which is shooting tiny projectiles.

Through the shop you can upgrade your weapon, the projectiles and your castle, but you can´t just buy what you want, you have to level up. Experience is gained by completing waves and money is earned for each zombie you defeat.

The daily reward system gives you a bit of extra money.
