The game is very difficult to control, even if you know what you’re supposed to do - though I do love the concept and it does get quite fun when you get the hang of it. I would suggest using mouse button dragging for moving the hand and autograbbing once the mouse button is released, that should be more intuitive. The walking only really worked if I dropped down a bit somewhere, so most of the time I was scaling even flat surfaces :-) Very funny game though, good work!
