Yeah, I should really add some slight forward velocity while in air so it isn't like that. You can still make it, since kicking allows for air control, but I don't think I made that clear enough. In fact, that seems to be the main issue for people playing, it's way harder than I intended since they're unaware of all the tricks. If/when I make a new demo, I ought to make a thorough playable tutorial, or at least a video to show off what one can do.
Thanks for giving it another try.
