Hi there!
Cool and unique submission. Like the combination of music and artwork. I love it when game jam teams work together to create their own assets rather than using pre-made assets - huge congrats and nicely done team! The music is the best I have heared in a long time, so I rated it 5 stars actually. I never liked platformers and that genre, but I am getting some nice feelings playing this one. Congratulations!
Improvement ideas/bugs:
If you jump up to the right in the first level, you can walk on invisble ground for eternity:D In the second level, my character was stuck at the spawning position and could not move. So I could not continue.
