Moomin: Midsummer Madness is heading to Nintendo Switch 2 this fall with a story built around one of Tove Jansson's best-known Moomin books. The adventure focuses on a flood, Snufkin going missing, and a strange floating theatre. These events are an important part of Moominsummer Madness.
Crossbridge Game Studios is developing the single-player point-and-click adventure for Switch 2, the original Switch, and PC. The exact release date and price are still unannounced, but physical editions are confirmed for both Nintendo systems. The latest trailer also shows more of the hand-painted world and its puzzles.

Moomintroll begins the story waiting for Snufkin to return, but a sudden flood quickly changes everything. Water covers Moominvalley and forces the family away from home. Their journey eventually leads to a floating theatre filled with costumes, props, scripts, and rooms that feel unlike anywhere else in the valley.
The game is inspired directly by Jansson's novel, giving the story a stronger base than a loose collection of familiar characters. The game includes important scenes from the book and adds new moments of its own. This gives fans familiar moments while keeping the story fresh.
The hand-painted art keeps the soft look of the original illustrations rather than using a shiny 3D style. Players will see places such as the Moominhouse alongside Midsummer celebrations and the old theatre. The flood changes how players reach these places, giving them a reason to keep exploring.

Moomintroll and Little My are the main playable characters, but other members of the cast can help during puzzles. Their abilities open routes that one character could not handle alone. Some characters can swim through flooded areas. Smaller characters can also fit through narrow spaces and reach hidden objects.
This gives the point-and-click format more variety without turning the game into an action adventure. Exploration, conversations, mini-games, and simple puzzles are still the main focus. The challenge comes from figuring out who can help and how to use the environment. Players do not need to learn complex controls or fight enemies.
A built-in hint system is designed to keep the experience friendly for younger players and newcomers. That suits a Moomin game, but the puzzles still need to be interesting enough for older fans. The best sections should make each character feel useful instead of treating their abilities like one-off tricks.
The fall 2026 release window was confirmed alongside the latest trailer, while the Steam page currently points to Q4. More details are still coming, so the biggest missing piece is the exact launch day. That will be important for players deciding between the Switch 2, original Switch, and PC versions.
Boxed copies are planned for both Nintendo consoles, giving collectors an option beyond downloading the game. Pricing has not been announced, and there is no word yet on whether either physical edition includes extra items. Those details will likely arrive closer to launch once the final date is set.
Moomin: Midsummer Madness already feels different from other licensed family games. Its story comes from one specific book, and the floating theatre gives the adventure a memorable setting. The game is set to launch in fall, with its story, exploration, and puzzle-focused gameplay at the centre of the experience.
