For the part where everyone says they can't kill the boss dealing with "here." Pay attention, because when he first rises in the air and splits, the original one flashes red real quick. As the bar then moves from left to right, you have to hit the up, left, or right arrow, depending on what spot the "1st" ninja is in. This will then cause you to throw your sword in that direction - according to where you clicked your katana "HERE!"
I love how the description says "can you spell ‘Ninja’? We sure hope so, because spelling correctly and quickly is the only way to stave off this martial arts onslaught." Especially since one ninja came at me named "heros."
Good concept, but when I;m on the far left side of the screen, and the gap's on the far right - there's not enough time to make it. Games like this have to always have an escape; if they don't then there's a programming error - or programmer error . . .
