Great work, I haven't seen a free running game in a jam before!
I did struggle with the hold and release space to climb up a wall mechanic, I'd recommend a little more feedback for when your character can climb or when it is holding on to the wall.
I'm not used to releasing spacebar doing things like jumping off the wall I'm running on either, I was instinctively releasing it early, turning to where I wanted to jump and pressing it again, which didn't work.
Nice entry, very creative!
