The main problem of this game, that made me stop playing, is that you know you will die. I mean, in a RPG, your goal is to be the hero, to seek glory or to save the world... But in this game... there's nothing... you don't know what you are doing there and you just keep moving and killing until you die. The game is good, though.
Good game! Way better than Papa's Pizzeria (which was really good). The upgrade system is a nice add, but i think it would be cool if i was able to hire some people.
