Estoty LLC is the developer and publisher of The Missing Tail, a two-player cozy co-op adventure in which both players control cats exploring a medieval castle and courtyard. The game does not yet have a release date.

Its notable design choice is accessibility of setup rather than of mechanics: split-screen and online co-op are both supported, and the game is built for two players sharing a single copy, which removes the usual barrier to a spontaneous co-op session.
