I just finished A Story About My Uncle ... crap name, great game. You have to do some major Spiderman style swinging moves in the last levels, it got really tough there. I almost said "

it! I don't want to find my Uncle anyway. He's a douche for leaving his family and he always gave me really crappy Christmas gifts" but I persisted and after finally making it through an extremely difficult series of ice caves sure enough I found Uncle Fred. I guess he was eating ice, I dunno how else he had survived so long down there.
It's a very unique game, it's kinda like Portal mixed with Spiderman. It's definitely fun, when you get the hang of swinging around with your crystal powered grapple glove some of the moves you'll make getting to the next platform are exhilarating and you get great satisfaction (and relief) in making it to the next checkpoint.
The achievements are kinda tough on the game. Even though I finished the game, and it was very challenging to do so, I only ended up with 1 of 15 achievements. I guess I could replay the levels for cheevos, trying to complete levels with less grapple moves and without falling, but as a wise woman once said ... "Ain't nobody got time fo dat"
I'd give it an 8.5/10
