I couldn't climb up past the first few ledges. I couldn't figure out how the climbing stuff was supposed to work. I like the look of it though.

You can jump again while hooked to a wall and the hook is dragging you, the moment you reach the wall you can't anymore and will fall though so you'll want to get some distance and be quick about that second jump. It seems a lot of people are trying to jump off of the hook too late. I hope adding some leeway to it and adding a little tutorial telling you what situations you can jump in will fix that.
