Very fun cute little game, I was expecting a bit of clunkiness given the ps1 aesthetic but it was surprisingly smooth. The level design was good in the sense that my next objective was always intuitive without needing any special direction. I also thought the little touch where the drums fade in when you collect the triangle things or smash things with the speed boost was very cute. All in all a nice experience.
One weird thing I did experience was that windows told me the game was trying to access the internet when I left the starting room. I don't know if this is intentional but the game worked fine for me with it blocked, but a popup like that in what appears to be a completely single player game does seem quite sketchy, so if that's not intentional then I would highly recommend looking in to what causes that to happen, or if it is it'd be nice if it was made clear somewhere what it uses that for.
