 With each successive floor, the speed and intelligence of the pirates increases.For every sixteen barrels Momotaro destroys, he will be rewarded with an item that grants invincibility for a limited amount of time, allowing him to defeat enemies by simply touching them.Momotaro's enemies do not have attacks, but a single touch from an enemy will cause him to die and be revived, costing the player one of his/her extra lives; the game will be over when he or she has no more lives.
