this game makes my brain hurt. ward 3 is pain in the ass
I thought it's tricky to play on Steamdeck, so I moved to desktop. Somehow Steamdeck actually performed better in comparison, but not enough for me to continue playing. Sad, happy to try it again once the devs will fix it.
Sanatorium – A Mental Asylum Simulator is a management game that immediately separates itself from most titles in the genre through its oppressive atmosphere and morally uncomfortable themes. Rather than placing players in charge of a cheerful business or efficient hospital, the game drops them into a bleak 1920s mental institution filled with paranoia, questionable treatments, political pressure, and hidden secrets. From the beginning, there is a constant feeling that something is deeply wrong inside the walls of Castle Woods Sanatorium. Players are not simply managing patients and resources; they are navigating a dangerous environment where every decision can affect lives while also threatening to expose their own hidden identity. The result is a dark and psychologically engaging experience that feels far more intense than a typical simulation game. The gameplay revolves around diagnosing and treating patients through a card-based system that gradually becomes more complex as the story progresses. Symptoms, procedures, medications, and patient conditions are all represented through cards that must be managed strategically. What initially feels like a straightforward management mechanic slowly develops into something much deeper because every treatment choice carries consequences. Some methods may stabilize patients quickly but rely on ethically disturbing practices, while safer approaches require more time and resources. This creates a constant moral tension where efficiency often clashes with humanity, forcing players to think carefully about how far they are willing to go in order to maintain control of the institution. One of the strongest parts of the game is its atmosphere. The sanatorium itself feels cold, isolated, and emotionally draining in a way that perfectly matches the themes of the story. Dimly lit corridors, decaying offices, and unsettling patient rooms create an environment that constantly feels oppressive. The visual design may not rely on advanced graphics, but it uses color, lighting, and environmental details effectively to establish mood. Every part of the institution feels filled with secrets and emotional decay, making exploration and patient interactions feel uncomfortable in the best possible way. The audio design contributes heavily to the immersion as well. Soft ambient sounds, distant noises, and haunting jazz-inspired music create a constant sense of unease that follows the player throughout the campaign. The soundtrack shifts naturally between quieter management moments and more emotionally intense scenes, helping the game maintain psychological tension even when players are simply reviewing patient files or organizing treatments. Combined with the oppressive visuals, the sound design makes the entire experience feel disturbingly immersive. The narrative is another major highlight because the game avoids treating its darker themes in a simplistic or exaggerated way. Instead of relying purely on shock value, the story explores institutional corruption, mental illness, political influence, and personal morality through patient stories and staff interactions. Many of the patients feel tragic rather than monstrous, and learning about their histories gradually becomes one of the most emotionally engaging parts of the game. The player’s hidden identity also adds another layer of suspense because there is always a sense that one mistake could unravel everything. This combination of management gameplay and psychological storytelling gives the experience far more emotional weight than most simulation games. Mechanically, the game succeeds because it balances strategy and narrative progression effectively. Diagnosing patients often feels like solving investigations where players must analyze symptoms, choose examinations, and determine the best course of treatment. Resources are limited, time is valuable, and mistakes can lead to disastrous outcomes. This creates a satisfying gameplay loop where every patient presents a new challenge. Endless Mode also adds replay value by allowing players to focus more heavily on optimization and experimentation without following the main narrative structure. The presentation overall fits the setting extremely well. Menus resemble old medical documents, card designs are easy to understand, and the interface reinforces the historical atmosphere without becoming overly complicated. There is a clear effort to immerse players in the role of managing an institution during a deeply flawed period of medical history. The game’s style remains consistent from beginning to end, helping the dark themes feel believable and grounded. However, the game does have several weaknesses. The pacing can occasionally become repetitive during longer management stretches where players cycle through similar procedures repeatedly. Some mechanics are not explained particularly well, causing the early hours to feel more confusing than necessary. Certain card combinations and treatment methods also become noticeably more effective than others, which reduces strategic variety once players discover optimal solutions. Technical issues such as interface inconsistencies, occasional bugs, and performance hiccups can also interrupt immersion at times. The subject matter itself will likely be divisive for many players. The game deliberately explores disturbing historical practices involving mental health treatment and institutional abuse, and it rarely offers emotional relief from its grim atmosphere. Some scenes can feel emotionally exhausting because the game constantly forces players into morally questionable situations. While this discomfort is clearly intentional and contributes to the game’s identity, it also means the experience will not appeal to everyone. Despite these flaws, Sanatorium – A Mental Asylum Simulator succeeds because of how committed it is to its vision. It combines management systems, narrative storytelling, card-based mechanics, and psychological tension into something genuinely memorable. Very few simulation games manage to create this level of emotional discomfort while still remaining strategically engaging. The constant pressure of balancing ethics, survival, and institutional control gives the gameplay a unique intensity that stays with players long after the campaign ends. For players who enjoy dark management games, morally complex narratives, and strategy experiences with strong atmosphere, Sanatorium offers something genuinely different from the standard simulation formula. It is unsettling, emotionally heavy, and occasionally frustrating, but those qualities are also what make it so memorable. Beneath its grim setting is an ambitious and intelligent game that successfully transforms psychological tension into meaningful gameplay. Rating: 7/10
The game is a lot of fun and currently not too challenging in terms of managing the diagnosis, which I am grateful for. Unfortunately, quite a bit of bugs here and there, especially in Ward 4, which is frustrating as it is challenging enough already. Exploration is also very limited, though I did enjoy chatting with the gatekeeper for a while. All in all, quite fun, you can enjoy pretending to be a doctor, wearing a nice white coat, trying to juggle prescribing music, workouts, or ice baths. Great times
El juego está guapo con el rollo de atinar el tipo de enfermedad mental que tienen los pacientes y a la par, hacer la investigación en el sanatorio PERO hay varios bugs que se cargan el juego. Es la tercera vez que inicio partida y no hay manera. Uno de ellos hace que no puedas pasar de X punto. Te quedas con los mismos 3 pacientes los cuales no puedes darlos de alta y tampoco entran nuevos y tampoco puedes avanzar en la historia... Lo desinstalo y lo doy por terminado... Lo compré en un bundle, pero si no, ya hubiera solicitado el reembolso. Una pena porque no pinta mal.
I am really 50/50 on this game as a fan of the simulation/strategy genre. It is frustrating to see that there is a kernel of a great game hidden here, but the devs have just not done enough yet to bring it to life. The core gameplay idea of treating the patients, figuring out diagnoses and treatments is great. The setting is very stylish. The details in the setting are fun. But all these parts unfortunately do not yet come together to make a whole great game. I would say that it is about 70% there and hopefully its true potential will be realized. At this point though it's been more frustrating than fun for me personally, unfortunately.
Buggy game with confusing and repetitive gameplay, not recommended.
nice
Close to being a good game, but has so many weird little issues that keep it from being real primo stuff. 1. Every night, you can go exploring around the hospital. Unfortunately, most of the time there's absolutely nothing to do or see. Just doesn't seem very padded out, more of a time-waster than additional gameplay. 2. I swear the pipes broke every single night on the third ward. Having random events is great, but having the same random event every night gives for an unpolished feel. 3. The diagnoses were kinda weird and hard to make sense of or utilize. I get what they're supposed to do, but there were so many and yet I felt like I hardly ever used them at the same time. 4. Let me pick up the folder I just put down, omg! Several hours of fun before the wheels fall off. Not a lot of games like this, I don't regret buying or playing but it's too screwy to recommend to people.
Original et sympathique (dans une vision ludique !). Avec un petit mystère à résoudre. J'aime beaucoup.
