CaTHaRSiS: The last of atelier, an art adventure from developer Mana and publisher Kodansha that lets you walk around inside famous paintings, has a release date. It launches on PC via Steam on Tuesday, December 1, 2026. The team also confirmed that the full game will ship with a Photo Mode, added after demo players asked for a way to frame the painted worlds themselves.
What CaTHaRSiS actually is
The pitch is simple. Most games that draw on fine art treat paintings as something to look at: a texture on a wall or a collectible in a menu. CaTHaRSiS puts you on the other side of the frame. You play an empty vessel with no memory and no sense of self, and you wander through canvas worlds built from well-known masterpieces, collecting the fragments of memory hidden in each one.
You don't go alone. Two companions travel with you, a wolf and an owl, and they help guide you through each painting. The developer calls it an immersive art adventure, and its own description of the genre is more direct: it's a walking simulator. There are no game overs and no timers. The studio says the whole trip through all ten worlds runs about as long as a feature film, so it's built to be finished in an evening or two.
Ten worlds, from Van Gogh to Klimt
Ten paintings make up the game's stages, and the store page names several of the artists and works involved. Vincent van Gogh gets the most room: one world combines The Starry Night, Café Terrace at Night and Sunflowers into a deep-blue night scene where yellow blooms stand out against a sky full of stars, and the route ends at a lone table under a café light. The hero image above comes from that stage. It shows the crescent moon and the speckled sky turned into a 3D space you can stand in.
Claude Monet's Woman with a Parasol becomes a sunlit meadow that seems to go on forever, and the developer pitches it as a place for nothing more than running through the grass. Gustav Klimt's The Kiss goes the other way: a space covered in gold leaf and geometric patterns, which the game uses for its most explicitly emotional beat, the vessel starting to grasp something like love.
The demo, which went live ahead of October's Steam Next Fest, covered two stages: the Van Gogh night world and one based on John Everett Millais's Ophelia. Those were the stages the team took to Tokyo Game Show, and they show that the line-up goes beyond the Impressionists and the Vienna Secession into Pre-Raphaelite work as well. The other stages haven't been named yet, beyond the developer's note that the ten draw on Van Gogh, Monet, Klimt "and more."
Photo Mode is coming at launch
The new addition for the full release is a Photo Mode, and it was added in direct response to demo feedback. Players said they wanted to capture the environments from any angle and to recreate the compositions of the original paintings inside the game, which is an obvious thing to want from a game whose whole hook is being inside the paintings.
Activating it pauses the game and frees the camera. You can move and angle the shot, adjust brightness, and hide characters so the scene is just the painted world. Mana notes that Photo Mode is part of the full game only and won't be added to the existing demo.
PC specs and platforms
CaTHaRSiS is coming to PC only, via Steam. Pricing hasn't appeared on the store page yet. The listed minimum requirements are steep for a short walking game, which suggests the team is pushing hard on lighting and particle effects to sell the painterly look:
- OS: Windows 11, 64-bit
- Processor: Intel Core i5-12600K
- Memory: 16 GB RAM
- Graphics: NVIDIA GeForce RTX 3060 Ti
Those are the minimum specs, not the recommended ones, so anyone on older hardware should try the free demo before December 1 to see how it runs.
Why it's worth keeping an eye on
Games that adapt art history usually do it as a puzzle backdrop or an educational add-on. CaTHaRSiS treats the paintings as places, and it's short enough that the gimmick doesn't have to carry dozens of hours. Kodansha has been building up a small indie publishing slate, and this is one of its more distinctive picks: a quiet, film-length game with no fail states, built around stepping inside canvases that most players already know by sight.
The demo is available on Steam now, and the full game follows on December 1.
