You are the shark. When it is your turn, at the bottom of the screen you will see three buttons: Attack, Special Attack, and Heal. --ATTACK: Attack your opponent with a weak attack. Uses up a little bit of SP. (Cannot be used if SP is too low.) --SPECIAL ATTACK: Attack your opponent with a strong attack. Uses up a lot of SP. (Cannot be used if SP is too low.) --HEAL: Regain a little bit of HP and SP. --After you take an action, it is your opponent's turn. They will either attack or heal, depending on their SP.
