It's an impressive VN, being made using RPG Maker MZ. I liked that even though it's a visual novel, it still had a lot of gameplay elements, the combat being the spotlight, I just think it could be tweaked a bit as some fights felt too long and the rhythm minigame can get pretty challenging, which isn't a bad thing in itself, mind you 
The art is also really good and I liked the variety in combat music, good job!
