Great job. Using the rhythm game controls for combat adds a layer of flair that isn't often seen. The audio when hitting the correct inputs was very satisfying. I would have liked to see some feedback on the enemies taking damage. I wasn't sure if was successful in my attacks for a while until the enemies disappeared.
Is there a way to choose the combat abilities with the keyboard? I kept having to switch to my mouse to select them which felt a little awkward because the rest of the game worked well with keyboard.
Over all very well done!
