If you still need someone to contribute music, I'm totally on board. I've already done a soundtrack for another game in this jam, which can be found here: https://www.youtube.com/watch?v=Bf8kDL5U3lU
Other examples of my work in various styles:
An upbeat and energetic Mario Kart-like song

Airy and dreamlike, inspired by Qbeh-1

Bright and open RPG town theme

Let me know if you're interested in having me join on the project
