Title pretty much says it. Super cute game, super short. I think part of the adorableness is imagining everything at the scale described in the game. Just trying to picture the tiny little ninjas made me happy. I liked that they were also given their own little personalities with the bit of dialogue they had.
I loved it, but you need to know what you're in for. Takes maybe about 10 minutes. The "puzzles" are very straightforward and the game dialogue guides you through pretty well.
