The player controls Neku by performing touchscreen actions based on the currently equipped pins. These actions may include slashing across an enemy, tapping the screen rapidly to fire bullets, holding down on an enemy to inflict damage or shouting into the microphone to cause a full screen attack. Other pins need to be touched to activate them, such as for health restoration. Each pin has a limited number of uses before it must recharge for a certain time. Other pins may only be used a fixed number of times during a series of battles, and do not recharge until the battle sequence is over. Neku can only be equipped with a maximum of two pins at the game's start; this can eventually be upgraded to a maximum of six.
