This game has so much potential, keep adding to it cause it will become a gold mind. Also please do not become one of those guys who demand cash for things. 5/5 and favorited.
You should have an option to kill the guards. By this I mean have a check box or something in the menu where if you check it you can kill the guards so it pleases those who want that ability and the great part about it being strictly optional is that those who want a real challenge don't need to use it/
