After you select a weapon, keep clicking its icon until you have the maximum amount of ammunition. Every time you click it, you will get the amount of ammo that comes with the weapon, but will not lose any coins.
Money
You will get money for every enemy killed. If they are not killed they will damage your Mario World castle. Use money to buy bigger and better weapons to avoid being overrun. Try saving your money for the end of the next round to buy bigger weapons.
