I enjoyed the platforming. I don't know if it was just me, but it felt like there wasn't a constant velocity when moving the player. Rather, it felt like I started slow but sped up as I continued to move until I was going to fast. More variety in the platforms and obstacles would add more diversity in level design but that might be out of scope for a game jam.
Good work on designing the platforming, some levels were hard but that made it more fun to beat!
