Great game! I really like the mechanic, artstyle, and music- it's just about hit everything for me! It has a surprising amount of detail in the gameplay- maybe i'll see if there's anymore extra animations for a 150+ combo lol. I really appreciate how it's in the "very doable if you take the time to learn it" category of difficulty.
EDIT: One more thing- If there's any criticism I'd give, I'd say that the note animations (the text coming up when you hit a note) is a little bit too sluggish compared to the rest of the game. Toning down the fade-in of them a little bit should make hitting notes feel a lot snappier.
