This is a rip-off. The original game, http://www.kongregate.com/games/nicotuason/dojo-of-death, is far from this one.
Seems that this developer just wants to ride on with the success of another. Please do not support this game.
Summary: This game is a ripoff. Not the same developer as the first.
Waaaa! Please don't post answers here! Let others feel the challenge.
The lack of a speed up button was intentional because some of my students do trial and error :D
