The game centres around its protagonist, Yarny, a small, apple-sized creature made of red yarn. Yarny explores the world around him that makes small everyday things look large due to his small size. By using the yarn his body is made of, Yarny creates rope to form bridges, pull things, and swing from items. His yarn is the main medium used to solve complex puzzles. As Yarny moves, the twine which he is made of unravels, creating lines that the player must use to solve puzzles to progress through the game. It also serves as an extra challenge, because if he walks too far, he will unravel into a basic frame. This frame can be refilled by interacting with balls of red yarn in the game. On this mechanic, Sahlin has stated, "It's always fun to play with physics. It's not just about solving puzzles. It's also a big part of how you move. Sometimes it's just traversing, navigating. Since you always leave this trail behind you, you can always grab it and climb on it and swing on it. You can do these really cool things when you combine stuff.
