Really?
It's a good cause and all but...
-The gameplay is TERRIBLE. You could hold right and up and it'd beat the whole game for you.
-There's absolutely no challenge, it's just run, jump, repeat.
-When the guy is falling, it looks like someone is giving him a... *ahem*
-Their heads were too big, I can understand big heads, but these ones were massive, and the faces weren't even decent.
-Sure, the wall grabbing was interesting, but it's been done so many times. This also isn't Prototype or spiderman, you can't just jump straight up a wall by grabbing it with your hands.
So yeah, sure it's for cancer research, but I'm pretty sure they're not going to go run on rooves and climb through people's buildings to get coins. You might as well have made it a flat running game where you spam the left and right arrow keys to run fast, because it'd be just as terrible.
