Yeah, when you pick up the wall jump ability that includes wall grab + climb as well :) We'll maybe add something to make it clearer that when you pick that item up it unlocks all of the wall-related abilities and not just wall jump.
I like the idea of expanding the abilities page to help make the abilities you've currently unlocked clearer, so we'll maybe have a look into that!
Glad you managed to get past it, just let us know if you encounter any bugs or the likes :D
Thanks again!
