Grimm is a Windows-based game developed by Spicy Horse, known for their work on American McGee's Alice. This game consists of 23 episodes, each based on a different fairy tale by the Grimm brothers or other authors. The protagonist, a dwarf named Grimm, interferes with the plot and tries to make the stories darker and grittier. The gameplay involves converting characters and objects into their dark versions to alter the storylines, all while the characters try to revert Grimm's magic to make the tales sweet again.

The game's style is comical, with a sense of black humor. The simplistic geometric 3D design and whimsical music add to the childlike atmosphere of the game. Grimm is a perfect choice for those who enjoy dark fairy tales and want to see a different take on classic stories.
