9:23 on level 1. made up of about 1 min. to get to the first check point. 2 for the second, and 6 1/2 for that jump. After that I stopped bothering. Level 2's design for the first section doesn't make sense. You've got a deep alcove that the player can easily get stuck in after the first two ledges, which would imply that it's a separate challenge from the first two ledges, yet you've also got the checkpoint being after that. I'm not sure what the point is for the ledges to be overhangs, as the 1 tile gaps are just an opportunity to get stuck with no addition to the challenge. Level 3 just seemed obtuse.

It's certainly an interesting idea, but I feel like you've stumbled into a design space that is inherently unusable due to chaos theory. I spent a while trying to find a set way of climbing the first two ledges in level 2 via measuring a spot against the flag and holding "d". The best I could find was a way that only works 1/3 of the time, and still requires mid-flight judgement for whether to let go at the last moment.

That's not to say the revolving mechanic couldn't be good, but if you try to use it again, I recommend the levels be more silly rather skill. The lack of control would need to be countered by some regular release of frustration, such as people panicking because a giant hockey puck is ruining their town,
