Moomin Midsummer Madness Release Date: Switch, Switch 2, Demo and Characters

The Moomin Midsummer Madness release date was Thursday, 12 November 2026. The point-and-click adventure is now available on Nintendo Switch, Nintendo Switch 2 and PC through Steam. There’s also a free demo on both Nintendo consoles if you’d rather try it before buying.

Inspired by Tove Jansson’s Moominsummer Madness, it follows Moomintroll and Little My through a flooded Moominvalley. Expect familiar characters, gentle puzzles and a rather unusual floating theatre. Here’s where to play it, how to get the demo and what to check before choosing a Switch version.

Moomin Midsummer Madness Release Date and Platforms

The Moomin Midsummer Madness release date is the same on all three platforms: 12 November 2026. Crossbridge Game Studios developed the adventure, while Shochiku published it for Switch, Switch 2 and Steam.

There are two Nintendo editions. The original Switch game runs on Switch 2 through backwards compatibility, but there’s also a separate native Switch 2 release. You don’t need to buy that newer edition just to play on a Switch 2, although the versions aren’t interchangeable when it comes to saves and add-ons.

Nintendo’s publisher notice is clear: there’s no Switch 2 Edition Upgrade Pass, and the two editions can’t share saves or DLC. If you already own the Switch version, don’t buy the native one expecting your progress to carry over. We’ve covered the differences in our Moomin Switch 2 upgrade and save compatibility guide.

Moomin Midsummer Madness Release Date: Where to Get the Free Demo

You can try the game on both Nintendo consoles before buying. Shochiku released the demos on 29 October 2026, ahead of the Moomin Midsummer Madness release date, and both eShop versions have a demo download.

1. Open the Nintendo eShop on your console.
2. Search for Moomin: Midsummer Madness.
3. Select the listing for the version you want to play.
4. Choose Download demo where the option appears.

The demo is worth playing if you’re unsure whether the slow, story-led puzzles are your thing. Shochiku hasn’t confirmed how much of the story it covers or whether your demo progress carries over, so don’t count on transferring a save into the full game.

Moomin Midsummer Madness Release Date: Story and Characters

A summer flood sweeps the Moomin family away from home and into a strange floating theatre full of costumes, scripts and surprises. Moomintroll and Little My need to find their friends and a way home, exploring the valley along the way.

The 1954 novel provides the starting point, but Shochiku says the game adds a new adventure alongside familiar scenes. You’ll visit Moominhouse and the old theatre, all drawn in a style inspired by Jansson’s illustrations. It looks much more like the books than a typical 3D game.

You don’t need to have read the novel before playing. Long-time fans will recognise characters and places, while newcomers can follow the adventure as a standalone story.

Can You Play as Moomintroll and Little My?

Yes. You’ll play as Moomintroll and Little My, using different abilities to get through obstacles and solve puzzles. The publisher describes characters who can swim or squeeze through narrow gaps, so there’s more to the adventure than clicking through conversations.

You’ll meet familiar faces including Snufkin, Fillyjonk and Emma, plus the wood children. But don’t mistake the cast for a menu of playable characters. The publisher hasn’t promised that everyone you meet can be controlled whenever you like.

What Is the Gameplay Like?

The game is a point-and-click adventure, with illustrated locations to explore, characters to chat to and clues to find. Puzzles and mini-games change as you move through the story.

There’s a built-in hint system, too. If you’ve been stuck in the same room for ages, you can ask for help instead of giving up or opening a walkthrough.

It’s much more about exploring and enjoying the characters than fast-paced action. That’s exactly why I’d try the demo first if you’re unsure.

Moomin Midsummer Madness Release Date FAQ: Multiplayer and Download Size

Moomin: Midsummer Madness is single-player. Nintendo lists one player per system, and the publisher does not advertise a two-player co-op mode. Someone can watch and help spot clues, of course, but you won’t each be controlling a character.

On the UK Nintendo Switch page, the estimated download size is 1.7 GB and the age rating is PEGI 3. Switch 2 and other regions can show different storage estimates, so check your own eShop listing before installing.

If you’ve been looking up the Moomin Midsummer Madness release date before deciding to buy, you can play it now on all three platforms. Try the free console demo first, and double-check which Nintendo edition you’re purchasing if you have a Switch 2.
