Anyone having problems with the Ninja game at the higher difficulty levels?  If so, then maybe this will help out...

After quite a bit of frustration, I found a way to get through the Ninja game a lot easier.  Instead of trying to track every ninja independently, stare at the middle square in the grid and don't look away from it.  Watch the ninja movement with your peripheral vision until they are done, but don't look up at the question when it pops up...use your peripheral for that as well to see the color they are asking for.  Picking the square that has that color ninja in it is a lot easier that way, especially if you do it quickly and go with your first thought.  It may take a little practice, but it's pretty much the only way to do it, unless you can move your eyes at the speed of light...or if you are color blind!
