They can use the ACT option to perform various actions, which vary depending on the enemy. Killing enemies will cause the player to earn EXP (in turn increasing their LOVE) and gold. Players may choose to attack the enemy, which involves timed button presses. As the game progresses, new elements are introduced, such as colored obstacles, and boss battles which change the way players control the heart. During battles, players control a small heart which represents their soul, and must avoid attacks unleashed by the opposing monster in a similar fashion to a bullet hell shooter.
When players encounter enemies in either scripted events or random encounters, they enter a battle mode.
