Moomintroll: Winter’s Warmth launches on PlayStation 5 on September 18, bringing Hyper Games’ snowy puzzle adventure to players just as its story begins: Moomintroll wakes from hibernation while winter still covers Moominvalley. The game’s creator says the goal is to bring back spring, wake the sleeping family and reunite with Snufkin. For wider platform context, our look at PlayStation’s PC strategy explains how Sony’s platform plans have changed over time.
Hyper Games describes the project as its second Moomin game after Snufkin: Melody of Moominvalley. The new adventure draws on Tove Jansson’s characters and visual language, but it is not presented as a simple retelling. It follows Moomintroll through a winter that has lingered too long, using exploration, environmental puzzles and a storybook presentation to build its version of Moominvalley. The official PlayStation store page lists the game’s PS5 release.
A storybook made from shapes and paint
Hyper Games says the look combines 3D shapes with painted 2D elements. The studio wanted the result to resemble watercolor on paper, including the uneven tint and texture that make a hand-painted surface feel different from a clean digital render. That approach gives the game a distinct visual identity without abandoning the depth and camera movement expected from a modern 3D adventure.
The presentation also ties the game back to details from Jansson’s work. The developer points to references to familiar characters and stories throughout the environments, including the Ancestor and the Hattifatteners appearing on a carpet. A red chair and an X-ray of Moomintroll are among the smaller details that players can spot while moving through the house and its surrounding spaces.
That attention to the source material places Winter’s Warmth alongside the kind of carefully authored indie games we have highlighted in our guide to indie games players may have missed. It is also a reminder that a licensed setting can be used for a new story rather than treated as decoration around a familiar name.
Snow that changes when Moomintroll moves
The most specific technical detail in the announcement concerns the snow. Hyper Games built the terrain from simple forms and added a deformable layer that reacts to characters and other objects. As Moomintroll moves through it, the snow is pushed up and displaced with visible weight. The studio says the effect is designed to make the player feel as if they are really walking through a soft, textured surface rather than crossing a static white floor.
The same idea extends to the game’s environmental staging. Bushes use flat forms that can resemble theater props, while perspective and camera angles create the illusion of a larger, more tactile landscape. The approach is deliberately economical, but the goal is not minimalism for its own sake. It lets the game preserve the illustrated feel of the Moomin books while giving the world enough movement to respond to the player.
Hyper Games says the story explores the warmth and melancholy associated with Moominvalley, including the emotional complexity behind Jansson’s work. Players will encounter Too-Ticky, a character inspired by Jansson’s life partner Tuulikki Pietilä, as Moomintroll searches for a way to end the long winter.
Moomintroll: Winter’s Warmth arrives on PS5 on September 18. The studio has invited players to look for its art references, environmental details and snow effects as they move through the adventure.
