It's a fun game (i love rhythm games) ,but there are some things you could improve on! It took me so long to realise it was timed, I kept pressing the middle button. I would move the timer at the start to above the bell, since it's confusing with your tutorial. And then don't reset to night 1 every night, it gets tedious after a while ;)
Still, cool art, cool vibe and it plays wel!
