I would like it better if the rules about upgrading/#of fighters were like this: Everyone starts with eight players. You can delete them and pick diffrent ones if you want. Points do not get added if you delete a fighter, nor do they get taken away if you add a fighter. You get 1-3 points when you win a person. You lose 1 point if you lose a person. Those points can be used to upgrade your fighters/healers.
Yes you really should let us buy extra stuff... maybe more toppings? or a station where you can put decors on your pizza for extra money when the person asks for one? Or maybe a soda machine where people put in $1 and they get a drink... every level you have to pay to refill but you get a small ammount of money from that too?
