Really beautifull game you have here! Also creative way of approaching the jams theme with a really touching message. As someone already mentioned here, there was a bug with the "Try Again" button which made it impossible to press so I had to restart the game. Fortunately , it was at the beggining so I didn't have much to do ahah.
Just nitpicking at this point, but the characters speed can be quite slow sometimes, I think it could be a little bit faster.
Another thing I would suggest is to improve a little bit on the game navigation, I got lost a little bit sometimes because it wasn't really clear for me where to go and the doors didn't have any type of indication or prompt saying they were open other than the arrows. The piano door seemed like it had the arrow indication the whole time even when it was locked and it confused me a little bit and some scene transitions where a little bit confusing as well for me.
Visuals are nice and unique and made the game standout in that aspect. Even though the artstyle is not my style, I recognize the work done here.
Now the music, oooh the music is something special. Really loved the music along with the rythm games. Congratulations to the composer, he did an incredible job! Just a thing that kinda bothered me though is the fact the the mini games were not quite synced in properly with the music sometimes but that was not game breaking.
Overall the experience was really nice, loved the music, liked the rythm games (I'm a huge fan of this genre) and the message was really good and fitting to the theme. Congratulations on the submission and the amazing work!
