I think It's a good start. It really needs music. I also think it would be better if you added a level system. One endless wave can get boring. A shop were you can buy more guns and zombies that get progressivly harder would also be nice.
Great game.Nice classes and quests,but items (weapons,clothes,etc.) are very expensive! I also think that quests should give more spore. All in all amazing game ! rate up if you agree
Thanks for the reply! Gonna make the "Ground Death" Right away =)
