"Despair", not "Dispair". (Also "further" rather than "farther" but "farther" is not actually wrong.)
I was worried that I was going to struggle to play this, like Witchdoctor Duel, but I got a handle on it (ha!) quite quickly. The instructions are a bit misleading because you assume you have to click the hand and drag carefully all the way to a handle but you just need to click somewhere sort of near an arm and drag in the general direction, as long as the arrow is pointing where you want it to go. I think that's where other people may have struggled in that they didn't realise that as I didn't at first.
Once I could control it properly it was really fun. The mix of frustration and accomplishment is just right and - once I was pretty good at playing - the good games became almost meditative experiences as I figured out the angles and swung along (except for the times when the ragdoll had disintegration disco seizures but I know you know about that bug).
At first I was really confused as to why, when I grabbed the black handles, it said "Hope" and that seemed to be negative but after a while I realised it was saying "- Hope" and the others were saying "+ Strength" etc. Those symbols look like dots/bullet points and are really not easy to read, especially because when you're playing at the beginning you're focussed on trying to play so you only read the text with your peripheral vision. I'd recommend making those symbols more defined.
I wasn't bothered by the red handle until I read David's comment, because he's right, and now it does bother me a lot. Maybe make them yellow or orange?
The choice of music was really great and very much enhanced the experience. I liked how when you fall into the pit (which is a clever training area as well) the ragdoll flops down as a breathing sound plays in the audio, which I assume was a happy accident but it's still really perfect for the moment.

I was expecting more to the ending. I though maybe I was climbing the word "summit" or something - maybe I was and my perspective just wasn't broad enough - and that at the end it would show you the entire wall so you could see what it was and what you'd accomplished so that was slightly disappointing that it didn't happen but not majorly so.
In all this is a really great game and perfect for the theme. There's not much to improve - but I would like to have more to play if you want to work on a bigger version of the game (more levels or something like that).
