About the previous episode: Yoomurjak’s Ring
The story begins when Jonathan Hunt, a journalist from New York, arrives in the city of Eger in Hungary for a break. He has local ancestry and speaks the language, but this is not the only motive for his visit. In the heritage of his great-grandfather, the globetrotter professor Samuel Hunt (known from the Agon series), he found two letters dated back in 1898. The letters were from a somewhat lunatic Hungarian scientist about a time machine he claimed to be working on. The references point to Eger, and Jonathan wants to find out what happened to the man and his preposterous invention. But soon he realizes that someone is desperately trying to stop him…
About the development of Miazma
Like Yoomurjak’s Ring, this title is also an FMV adventure game, developed by the same crew. It takes you to real locations with live-action cinematic approach. The game designer is Pierrot, also known for his adventure game series Agon.
Miazma was developed with the support of the Institute for Nuclear Research of the Hungarian Academy of Sciences (Atomki) in the framework of scientific project Understandable-available physics. English localization was supported by EPS, NuPECC and ENSAR2. Additional supporters: KIA Motors Hungary.

Well this sucks! Anyone else notice the pattern of Steam creators who make an otherwise good game, players encounter a game breaking bug, then the developer disappears and never answers?! This WAS a very good FMV - not cheesy, good locations, characters, story etc - then I encountered the PLASMA Puzzle and cannot progress. I even used the Skip button but it doesn't let you progress. My gripes are.. cut-scene with every location change (once would have been enough!), Too many locations available, only to be the wrong one which creates lots of unnecessary backtracking for no reason, too many objects with too many characters only for them to say, I don't know about this. Most of the puzzles were just mega difficult or completely dumb. And never ever an in-game hint about what to do or where to go next. Not even the slightest nudge. But despite all of this, it was a very good game up until the bug. IS THE DEVELOPER EVER GOING TO ADDRESS THIS??!!!

I really enjoyed Miazma: The Devil's Stone and honestly think it was better than the first game. the story picks up in a cool way, and the voice acting was pretty great, which made the characters feel more understandable, and you weren't too late with reading the subs, lol. the devs didn’t exactly expand on the original concept (about the main character etc.), but it still felt like another good part of the story. the gameplay and visuals also got a nice boost compared with the first part. the only thing I didn’t enjoy was the last puzzle — it was pretty tough and kind of took away from the flow. as for Jonathan, the main character, I wasn’t a big fan of the fact that he was after so many women and seemed like a bit of a womanizer, which made him a little less likable. he also sometimes behaves very arrogantly, but I think that was just his character designed by the devs from the begining.
overall , if you’re into FMV games, I’d definitely say give this one a shot. it’s def a solid sequel,

Good FMV game from around 2007,
Pros: A big pacing and cinematography improvement from Yoomurjack's Ring.
There are some tough puzzles in here, but they are all in the last half.
Interesting use of Hungarian physics history
Cons: Mild amount of 90's level misogyny. All 3 women are physicists, but there's a weird demonstrative tone with them
Acting isn't great, but it's mid level compared to other FMVs

Miazma or the Devil’s Stone, developed by Private Moon Studios and published by M.INDIE, is a modern continuation of the classic live-action adventure format that blends mystery, science, and the supernatural through full-motion video storytelling. As a spiritual successor to Yoomurjak’s Ring, it revisits the investigative exploits of Jonathan Hunt, a journalist whose curiosity once again leads him into a labyrinth of strange disappearances and ancient secrets. Set primarily in Hungary, the game invites players to explore a world of cryptic scientific experiments, forgotten legends, and shadowy institutions, all centered on the mysterious “Devil’s Stone,” a meteorite shrouded in myth and danger. It’s an experience that wears its roots proudly, embracing the charm and ambition of traditional point-and-click adventures while translating them into an FMV framework that feels more cinematic than nostalgic.
From the moment the game begins, Miazma establishes a tone that is both grounded and unsettling. Jonathan Hunt arrives at a research institute where one of the scientists has mysteriously vanished, leaving behind a trail of clues that connect to a centuries-old artifact with potentially cosmic implications. The narrative cleverly intertwines real-world science with speculative fiction, balancing rational inquiry with mythological intrigue. As the story unfolds, it leads the player through a mixture of laboratories, observatories, crypts, and local landmarks, each with its own visual texture and cultural grounding. The storytelling is patient and deliberate, allowing moments of quiet observation and reflection between plot revelations. The mystery doesn’t rely on sensationalism but instead on an escalating sense of unease, as Jonathan begins to realize that the truth behind the Devil’s Stone may be more dangerous than any scientific curiosity.
What sets Miazma apart is its visual and stylistic commitment to realism. Every scene was filmed on location in Hungary, lending the game an authenticity that pre-rendered environments often lack. The live-action sequences are woven seamlessly into a point-and-click structure, with carefully framed camera angles, environmental details, and real actors giving the story a sense of tangible presence. The cinematography captures both the mundane and the mysterious with equal care—the sterile brightness of laboratories contrasts sharply with the eerie quiet of ancient ruins and candlelit corridors. Despite the modest budget, the production quality is commendable; Private Moon Studios clearly poured passion into the project. However, one unavoidable limitation lies in the dubbing. The actors perform in Hungarian, but the game features only English voice-overs, and the mismatch between lip movements and dialogue can be distracting. While the effort to make the game accessible to an international audience is admirable, many players have expressed a wish for an option to hear the original Hungarian performances with subtitles for a more natural experience.
The gameplay adheres to the logic of classic adventure design, but with a focus on accessibility and coherence. Players interact with environments through a simple point-and-click interface, using a contextual cursor to examine objects, collect items, and engage in conversation. Inventory management plays a central role, with puzzles often requiring the combination of scientific instruments or documents to progress. The puzzles themselves vary widely—from decoding ciphered notes and repairing equipment to logical deduction and environmental problem-solving. Some of them are elegant and rewarding, while others can veer into frustrating territory due to obscure logic or missing hints. Still, the game maintains a careful balance between challenge and narrative flow. For those who prefer a more streamlined experience, an easy mode highlights interactive hotspots and offers optional assistance. This design choice makes Miazma approachable without diluting its puzzle-solving depth.
The pacing of Miazma reflects its hybrid nature as both a cinematic experience and an interactive mystery. Conversations are often long and deliberate, requiring attentiveness to subtle details that may later influence progress. The inclusion of real science gives the dialogue a sense of intellectual credibility, though it occasionally borders on overexplanation. The game’s structure allows exploration of over thirty unique locations and interactions with more than twenty characters, each with a role to play in the larger web of intrigue. Some characters feel like archetypes—the skeptical scientist, the evasive bureaucrat, the kindly local—but the performances are earnest enough to make them memorable. While the overall narrative is engaging, the ending arrives too abruptly, resolving key plot threads in quick succession and leaving a few questions unanswered. It’s a flaw that slightly undercuts the carefully built momentum, but not enough to overshadow the journey itself.
Audiovisually, Miazma does an admirable job of enhancing immersion through sound and score. The music shifts between ambient electronics, melancholic piano melodies, and occasional retro influences that evoke classic adventure games from the 1990s. Some tracks feel unconventional within the context of the story, yet their variety contributes to the game’s distinctive mood. The sound design heightens the atmosphere: footsteps echo through empty corridors, machines hum in sterile rooms, and the wind outside carries a faint, foreboding whisper. These small details make the world feel alive, even when the player is simply standing still, trying to piece together the next step.
Miazma is not without its flaws, but it’s the kind of game whose imperfections are born from ambition rather than carelessness. The English dubbing can detract from immersion, a few puzzles can feel unnecessarily obtuse, and the narrative resolution could have used more breathing room. Yet beneath those surface-level issues lies a project crafted with genuine care for storytelling and design. Private Moon Studios demonstrates an understanding of what makes FMV adventures appealing—the intimacy of live performances, the immersion of real environments, and the slow-burning satisfaction of discovery. It’s a rare entry in a genre that has largely faded, and it stands as proof that full-motion video storytelling can still captivate when executed with sincerity.
For fans of mystery adventures and FMV storytelling, Miazma or the Devil’s Stone is a quiet triumph. It’s a game that values curiosity, observation, and deduction over reflexes or spectacle, offering an experience that feels both nostalgic and contemporary. It’s not about grand cinematic twists or shocking horror—it’s about atmosphere, intellect, and the slow unraveling of secrets buried in science and myth. While its flaws prevent it from reaching true greatness, it succeeds in delivering a distinctive and thoughtful experience that lingers long after the credits roll. Miazma is a testament to the enduring charm of the adventure genre, and a reminder that even in an age of constant spectacle, there is still room for games that ask you to think, to watch closely, and to believe in the mysteries that hide in plain sight.
