Just bought the game and had to afk after wave 3 and when I came back i had to start over. I am going to have to refund the game and review the game appropriately.....you cant save your game and there is no gamepad support.....if you are unable to allow game saves. Just let the game save every wave so if my kids start acting up like today...I can go tend to them and come back later. Real life matters Mr. Developer....
