Very unique mix between Rhythm Game and RPG. You are facing battles against visually stunning enemies and casting your attacks by completing rhythm sequences. Stronger attacks require longer combos. Cast offensive spells, heal your party members, etc...

Status effects are quite fun, too. Your notes start disappearing if you are "blind", or spin around if you are "dizzy"... It's really well done.

The OST was not quite my thing, but it wasn't terrible either.
