Hyper Games is supporting Moomintroll: Winter's Warmth across PS5, Switch, Switch 2, and Steam, with the PS5 version out as of September 18, 2026 and a 100 yen upgrade pass for Switch owners moving to Switch 2.
Hyper Games has moved from a single-platform release to a multi-platform one for Moomintroll: Winter's Warmth. The puzzle adventure, in which Moomin wakes from hibernation too early, came out on Switch and Steam on April 28, 2026. The PS5 version followed on September 18, 2026, priced at 2,550 yen. The studio is also offering Switch owners a 100 yen upgrade pass to the Switch 2 version, and the Switch and Switch 2 versions are 20 percent off at 2,040 yen through September 29.
The release expands the game's reach while keeping the price low for players already on Nintendo hardware. The upgrade pass covers the move from Switch to Switch 2, and the discount applies to both Switch and Switch 2 versions. The PS5 version is a separate purchase at 2,550 yen. Hyper Games worked with Kakehashi Games on the PS5 release.
Behind the release schedule, Hyper Games has described its own surprise at the franchise's reception in Japan. CEO Are Sundnes said in an interview that when the studio started making a Moomin game, he did not know the franchise was so popular in Japan. The team's sequel, Moomin Troll: Winter's Warmth, released on April 28. Sundnes said Japanese players became the studio's most important audience, a discovery that shaped their development approach.
