Thank you for the review, I agree that air movement is a need for this kind of game, I didn't feel it so slippery but for sure I'll give a look on that too, do you think that the movement speed is ok?
I would say the base movement speed is fine, it's mainly the friction that stood out to me. It's not terrible, but if you aren't used to it, it is noticable. I fell off the edge of a few platforms that I felt I shouldn't have because I kept moving a bit too much after I stopped.
