Short and funny VN with a small rhythm game section, good job! Extra kudos for not making it hours long ¦3
The animations and transitions are nicely done. The drawings are a bit simplistic, but they are all consistent to the game style.
Music selection is also pretty good. Sometimes the same music could restart from the beginning, and loops are not perfect, but these are all minor things.
Making a rhythm game is hard, and even if you picked the right tech for the job, I think the hardest part is to make the actual mapping of expected inputs to match the song. You can try recording yourself table drumming the rhythm section in the game, and then check how that recording fits the music.
Good effort, it was fun to see all 3 endings!
