Shochiku Games and Crossbridge Game Studios have confirmed the release date for Moomin: Midsummer Madness, a cosy point-and-click adventure adapted from Tove Jansson's 1954 novel Moominsummer Madness.
The game will launch digitally on the Nintendo eShop for both Nintendo Switch 2 and Nintendo Switch worldwide on 12 November 2026.
Background and development
Developers say the title draws directly from the atmosphere and narrative beats of Jansson's Nordic fantasy, centring on the Moomin family as they seek refuge in a mysterious floating theatre after a sudden flood overtakes Moominvalley.
Players control Moomintroll and Little My, navigating light puzzles, dialogue-driven exploration, and character interactions while the story blends classic episodes from the original book with newly written scenes.
Gameplay and presentation
Shochiku Games and Crossbridge Game Studios describe the experience as accessible to players of all ages.
The developers emphasise a gentle puzzle design supported by a hint system so that younger players or those preferring a relaxed pace can progress without frustration.
The title also features character swapping mechanics, allowing players to switch between Moomintroll and Little My and use their differing traits to overcome obstacles.
Visuals and faithfulness to the source
The team has committed to a hand-drawn aesthetic inspired by Tove Jansson's original illustrations.
According to the announcement, the game employs vibrant, hand-painted art to recreate locations such as the Moominhouse and the floating theatre while retaining the storybook feel of the source material.
