It challenges you, to see how far you can get. Some of them you really have to think about, i think it was level 8 that took me about 5 mins of thinking how the pattern works and stuff. A kid in my tech class has got to level 20 with only 14 deaths. Also, i think you think it is so stupid because you did not get very far lol. It isn't stupid imo, if you don't link it, fine, but doesn't mean everyone else is going to.
