Not sure if its intended or a bug, but when I was trying to P rank Senpai on erect. the highscore wouldn't change from 99%, and eventually the song will go back to the E rank due to the highscore being better then the P rank

though honestly may be me just coping for my fingers dying but hope this helps to see if this is intentional or a random bug

genuinely love this, its simple but absolutely charming to me, def gonna play this here and there when I have time to kill
