You May is a fangame by nyrator. It is currently only in beta. The name is a play on the common mispronunciation of "Yume". It is planned to have a parallel game called phthsc, but its development hasn't started yet.
You May starts off with a short cut scene; Afterwards you start in your room. Unlike most fangames you can leave your room. Yarn's house features a living room, a kitchen, a bathroom, and a hallway that leads into another room. Also unlike most fangames you don't sleep in a bed, you build a pillow fort to enter your dream world.
While inside of the home you are guided by a voice that asked to be called Choco; However, they cannot reach you while inside of the dream world and offers help (for a price) when you decide to return.
It's about "a young girl with a specific detrimental ailment causing her to seek her most prized possessions in her imaginational dreamland!" (from dev blog)
Yarn's Different Worlds StylesEdit
Similar to the way it is done in My Favorite, in certain worlds Yarn will become a different-styled version of herself. The various shapes she takes are not collectible effects.
