Gameplay
The games play as a turn-based RPG as you explore through the region, battling against enemies. The combat is rhythm based as every attack requires you to press buttons at the correct rhythm or else the attacks will cause less damage. Special attacks require MP (music points) and more fast and difficult button presses yet causes way more damage. The combat also allows you to block attacks by timing button pressed to mitigate damage. The games have a leveling system as after leveling up your characters gain more health and attack points. The games also have shops where you can buy items to heal and boost stats.
