Really cool mechanic with a solid design! I also appreciated the sleek graphics and presentation of the levels! You really nailed the visuals on this one :)
My one big gripe is that on the first level I had a pretty bad time with the spiky trap. At first I didn't really recognize it was a threat, but once I did I started having big issues working out the jump for the black ball. The hurt box felt a little rough, I think. However, I had a great time playing and would love to see this concept explored further post-jam! I think you could really go ham on this idea and release a nice full-sized puzzle game!
Good job!
