Awesome theming, with a cool gimmick to accompany it. Puts a whole spin on the memory level genre, but the fact that using a calculator is the most optimal completion technique means the gimmick wasn't executed perfectly. Whizkid's completion without a calculator, and him explaining his method made for a much more entertaining experience than the primary method. The atmosphere of the level is so representative of the ninja theme and this level is a 9/10 aside from the issues regarding the memorisation gimmick.
