Cute game! I enjoyed playing it.
Some things that you might want to change if you continue development after the jam (and I hope you do (if you want to lol)):
1. The music is generally not in sync with the arrows. I can emphasize with this, as syncing gameplay to an audio file is very difficult. Because of this, making a rhythm game for a game jam is very ambitious. The timing was very forgiving, so this didn't really cause me significant trouble while playing, but it would have gone a long way in keeping me in the zone.
2. There was never really a reason for me to look at the top half of the screen. In fact, doing so would just penalize me by making it hard to keep up with the action. The arrows don't match up with any particular asset, sometimes I have to press up for a door, other times I have to press down for a door. If the arrows were overlapping with the sprites somehow it would be easier to keep up with the rhythm game while enjoying the fantasy of adventure.
Nice work, and I'm impressed that you were able to add a networked high score table.
