My turn to apologize for a delayed reply :) I'm afraid it's the whole thing that doesn't work. When I start it, I just get the developer logos, then a screen with a large triangle-sort-of-robot symbol and the "press any key" text, which doesn't respond to anything I do with the controller.
With C-Robin the issue turned out to be that there were multiple controllers plugged in and the game got confused where input was coming from. Try disconnecting all controllers other than the one you want to play with, including wireless and wired controllers (and dongles). If it still does not work try removing all other USB devices and try again. Please restart your Xbox and try again if any of the above does not work the first try :)
