Finnish indie studio Hyper Games, which won Grand at the NYX Game Awards (2025) for its previous work ‘Snufkin: Melody of Moomin Valley’, has simultaneously released the healing puzzle adventure ‘Moomintroll: Winter’s Warmth’ on Steam, Nintendo Switch 1, and Nintendo Switch 2.

Inspired by Finnish author Tove Jansson’s *Winter in Moomin Valley*, this work tells the story of a Moomintroll who awakens alone from hibernation and grows as he explores an unfamiliar snowfield. The picture book It is characterized by a blend of watercolor-style visuals that resemble flipping pages and calm, puzzle-centered gameplay, allowing you to enjoy an emotional healing journey without stress.

Moomintroll’s First Winter Trip After Waking Up Alone

The game is inspired by Tove Jansson’s novel *Moominland Midwinter*. Moomintroll, who unexpectedly wakes up early from hibernation, finds himself alone for the first time in his life. The familiar Moomin Valley has transformed into a completely unfamiliar world, covered in frost created by the Lady of the Cold.

At first, the young Moomintroll, who longed for someone to look after him and wanted to drive away the winter, builds new friendships throughout his journey and gradually learns how to help those who need him more than he does. Players take on the role of the protagonist Moomintroll as they explore the snow-covered Moomin Valley and the surrounding forests and mountains, discovering together the meaning of the season of winter as they encounter it for the first time.

Visuals like turning the pages of a picture book, a cold yet warm sensibility

The game delicately captures Moomin’s unique sensibility with watercolor-style visuals inspired by Nordic nature. It is characterized by a presentation that feels like turning the pages of a picture book one by one.

The sound design also faithfully captures the atmosphere of the picture book. Gentle piano melodies and Moomintroll’s monologues, which play whenever you navigate the map, naturally portray the game’s mood. The pitch-black darkness inside Moomin House, just waking from hibernation, creates a subtle tension in the beginning, while a world with a pastel watercolor feel opens up the moment you step into Moomin Valley amidst a snowstorm.

97% Positive Demo Rating, “Precisely Capturing the Sensibility of Picture Books”

The game’s Steam demo achieved a ‘Very Positive’ rating, with 97% of the 172 reviews being positive. Users have commented that it feels like “walking through a picture book from childhood” and that it “successfully captures the unique sensibility of Moomin.”

The second Moomin adventure from the creators of ‘Snufkin’

Hyper Games is a Finnish indie studio that released its first Moomin game, ‘Snufkin: Melody of Moominvalley,’ in March 2024.

The development team stated that, as the licensee, they focused on faithfully recreating the atmosphere of the original work through close collaboration with the Moomin characters for six years.

‘Moomintroll: Warmth of Winter’ combines the unique warmth of the original work with the lyricism of the winter season, and is expected to provide an impressive experience to players who appreciate the sensitivity of the original and the healing adventure genre.
