Currently there doesn't seem to be any reward after clearing the level, which is kinda disappointing. Large bell (I think that's his name?) did cum after 100%ing the level, but the UI is still covering him so :/
I can understand that the patreon supporters will get exclusive contents. But locking the entire gallery while not giving any method of seeing the scenes is just cruel. I think we should at least get to see all his animations after clearing the level. Honestly with how hot the art is, focusing on the game is hard enough lol.
Still, this game looks really nice! The artwork/animation is on point and you can never go wrong with a classic rhythm game. Excited for future updates
