Snowball Fight is, as the title suggests, an action game where players take control of a boy who throws snowballs at his peers and other creatures. The aim of the game is to become the Snowball King, which means players must beat all the other characters using snowballs. The game starts on an area map where players have access to the first stage titled Eastern Boys, as well as to an Item Shop where they can buy limited use special weapons which can temporarily stun enemies or freeze them in place, and a Drugstore where players can buy items to restore their health during tough snowball fights. During combat, pressing 5 once will lock the protagonist in shooting position, while the second press, depending on the timing, will adjust how far the snowball will fly.
