Hey, it might be fun for...well, the heck of it. Just doing simple things, like accelerating in reverse infinitely, is fun to watch for a while.
aside from that, I could recommend quite a few other games to be streamed. Tonba, Mischief Makers, Gex (any one of them), Rocket Knight Adventures, and Dalmations 3 all come to mind...though, that last one might be more of a movie than a game...
DOY! I almost forgot. Why not steam Ori and the Blind Forest? I'm also interested in seeing Dust: an Elysian Tale streamed...Yeah, I think that's enough recommendations from me.
