Technomage... the problem Jason is having also affects your game, but its not a show stopper for you at this point (IMHO at least). As far as I can tell, your app gets the same message (unknown exception) when I select a cube, start the shoot-em-up, fail and try to leave the cube (and when I same the same message... I mean exactly the same).

I only raised it with Jason, because at the moment, we can't score his entry because it won't start, whereas yours works great... providing I don't leave a cube, but that won't stop me scoring it.
