Overall this is a very cool game! I love the art, mood, and especially the character design: the theming made for a very fun experience!
To give some feedback, on the last phase I didn't realize you could 'run' pressing W almost until the end, which made me progress slower through the level, ultimately making the music run out of time and leave me in silence for the last few seconds. 0 bugs though, the only thing I would fix is to make the song loop!
Great work, YellowfallGames!
