This is pretty neat although I kept struggling with the climbing mechanics since I kept thinking it was a toggle and that I had to hold on to the jump button. May recommend making the climb an optional toggle for those who struggle with the ability to hold a button down for a long time while perform other tasks? At first, I thought the crafting mechanic was going to be overwhelming but it ended up being pretty easy to manage and a nice addition.
One last thing, I wanted to jump UP off walls when I was climbing. That feels better ;) I want to change jumps and climbs to do cool climbing speeds strats :D
