Hahaha, oh man, i'm surprised that you've found the gliding button, that is broken as hell and i thought i removed it for the demo, but skipped the F to grapple button.
Thanks for the input, i'm glad you got the hang of it, looking at the videos people posted, i figured that the wallrun will not take your input if you're looking up, but that's how people want to wallrun up, so i already fixed that.
Thanks for making it a video too, it really helps to see all the ways people play the game going in blind.
