Hello!
I don't really see how it fits the theme (yeah, only one hand, I know, but it doesn't really matter from the games perspective, it would be the same with 2, 3 or even more hands).
That aside, the hand has a cool design and the moving between platforms feels good. Well, when they work properly, I jumped through the walls many times and died in the outer space... But, still for a 48 hour game, it's very impressive, I still really liked it! :)
