Short like all the other hidden cat games, but this ones better than most. The song isn't headache inducing and the art is very nice to look at. Also there's a color tool which you can use to customize how the doodles look! So if you're bored with the black and white doodles you can choose any color you would like for the outline, the background and the cats (or randomize it!) And for those having a hard time, there's a free hint system.
