As a huge fan of music, I'm loving this game so far! One piece of advice could be that when you start the game, could you put a slightly longer delay before you start beating up the enemies? Also, when the first two beats are slowed down but the rest are suddenly normal-paced, it kinda throws off my rhythm a bit, so maybe do something about that 😅 Other than that, this is an amazing game! I've already convinced one of my friends to download it (and become my rival) and I can't wait to see the full release!
Edit: Oh and also, maybe you can put a setting to reduce the blur? I tried playing this at 3 AM and I couldn't tell if I was just sleepy or if it's supposed to be like that ¯\_(ツ)_/¯
