Grimm is an interesting idea, make the new fairy tales that know no brutality, know no grossness, return to their origianal state. The artstyle is good, the effect of the happy pastel colors and fittingly sweet surroundings bring warped into a dark, industrial world is a good effect and make this game worth checking out.
The gameplay of Grimm is highly repetitive, walk around a map, make it gross, stomp objective, stop people from cleaning up after you
The main charcter "Grimm" is seemingly a one trick jokester revolving mainly around farts and is generally not likeable, however upon completing all the scenes of the game, you get to watch a mildly entertaing Grimm Fairy tale play out.
Overall the price is right, the first episode is free so no one feels like they are being scamed, and the other episodes are 99c, Personally, I think the artstyle and the ending story are worth it enough to give this game a try.
