What is available now
The game is designed around one player managing a farm, exploring, building relationships, and progressing through the town and mines. Steam Cloud and Family Sharing are listed, but neither feature turns the game into multiplayer.
What about future co-op?
This page does not treat community requests as a development promise. It will change only when an official source confirms a multiplayer feature or roadmap item.
