Overall I really enjoyed it, it totally gives OSU/Beat Saber type of vibes, however I would mainly say that this game is more of a memory game than a rythm game.
I couldn't even focus on the song itself and I felt like I wasn't really hitting the "empty spaces" when the beat was dropping.
And, Hard mode was lowkey easier than Normal Mode, or at least the beginning of it, I got further on Hard than on Normal
One suggestion would be to make the beams shorter in time but in such way so you hit it and move via music rather than memory and trial and error
Ggs to the developers tho, I can see myself playing this in the future more \o/
