The full game, developed by France-based Crossbridge Game Studios, is a point-and-click adventure based on Tove Jansson's Midsummer Madness. It follows Moomintroll as a great flood sweeps Moominvalley and the family drifts to a strange theater full of costumes and scripts. Puzzles and minigames use each character's abilities, such as swimming or slipping into narrow gaps. A hint system is included. The title is set for release on November 12, 2026 on PC, Nintendo Switch 2, and Nintendo Switch. Demos for the Switch versions are planned for a later date.
