Well then.
Seems i have a different opinion from the most of the reviews. Its odly addictive, and the lack of sound means i can play it at the same of my screen while doing other things, completed it a few times now and its perfect for those 20 second spots of blind boredom. I think the attempt at this along with the tower of epilepsy was a bit sneaky, plus i prefer this one as the flashyness of the other takes away from it simplicity.
