There is a surprising amount of polish for a 48 hour rhythm/music game here, visually at least. I liked that I got a sense my notes were being hit not just through the level of accuracy being displayed, but through the subtle animation of the now-bar / strike zone. I like the simple narrative you have goin as well and the art is really nice!
The big issue I found is that the polish may have come at the cost of gameplay? The detection of player input is good (a bit too leniant) but the inputs i'm hitting didn't really make me feel like I was actually playing to the beat or the music. It felt very much like a faux-rhythm game in that you're being awarded for pressing buttons accurately but they don't feel connected to the song at hand.
It's still a super impressive end result for a 48 hour jam though!
