Thank you for the feedback!
The physics do seem weird at first, the ceiling killing your momentum is purposeful since you're hitting the ceiling with backspin. Its a physics simulation and sometimes physics are counter-intuitive.
For the stuff I do want to fix, how do you suggest i deal with the camera? should I remove the slight zoom out when you speed up? I am teetering on that already.
As for the tutorial, I got a lot of feedback on that, and I plan do do a few more shorter advanced tutorials on momentum before hitting the ice, such as a safer and more easily repeatable jump to teach about killing your backspin before hitting a ceiling. I also plan on changing how the tutorial text is displayed by means of an interactive sign that shows a big text bubble instead.
I appreciate you giving it a go!
