This is really well done, congrats! The art style fits really well, as does the music and it succeeds in creating an emotional connection. I also liked the message and the movement, it's pretty snappy and well made. I had no trouble hearing the series of notes to play to open the doors, but sometimes the background music distracted me along the way and made me forget, so maybe it would be cool to fade out the volume a bit on those stretches, but I really enjoyed playing this nonetheless. Very nice!
