About

Sentenced to life in prison for your crimes, you’ve been given a rare and unexpected chance at freedom. The offer is simple but unsettling: participate in a highly experimental trial for a new drug designed to treat memory loss. In exchange, your sentence will be commuted. It’s an opportunity most would jump at, but nothing comes without a price.
The experiment seems straightforward. You’ll take the drug, enter an experiment room, and observe your surroundings. When you leave and return, you must identify what has changed and enter it into the computer system. Complete all three experiment rooms successfully, and you’ll earn your freedom.
But as the test progresses, the rooms begin to feel less like controlled environments and more like a nightmare. Is it the drug? The experiment? Or something more sinister lurking in the shadows?
Freedom is within your grasp, but can you trust your own mind to get you there?

Estimated Gameplay Time: Completion time varies, but the game is designed to be finished in approximately 3 hours or longer.
Explore Three Unique Rooms: Each room offers a distinct environment filled with dozens of object anomalies and events to discover.
Deadly Threats: Encounter many dangerous threats, each requiring a specific strategy to overcome. Failing to respond correctly will result in death.
Survive or Restart: Failing to identify anomalies correctly will cost you lives. If you run out of lives, you’ll be killed and must restart from the beginning of the current room.
Room Progression: Successfully completing a room unlocks the next. To finish the game, you must unlock and complete all three rooms and face a final task.
Permanent Room Unlocks: Progression is permanent; once a room is unlocked, it remains accessible, allowing you to restart from that room without needing to replay previous sections.

Calificación 7.5/10 Es un juego que al principio parece injusto. Lo jugué una vez, terminé frustrado, pero al siguiente día me ♥♥♥♥ a pensar en cómo podría resolver las anomalías. El juego va como muchos otros de identificar anomalías, pero le agrega un aspecto extra que es que tiene amenazas "activas" que aparecen en el mapa para dificultar u obligarte a identificar mas rápido dichas anomalías (dichas amenazas no cuentan como anomalías en si). Al principio como digo parece frustrante, pero la idea del juego es ir aprendiendo de las amenazas y saber como enfrentarlas. De momento he jugado poco menos de 2 horas y uno de los puntos mas débiles es que siento que le falta optimización, ya que en varios puntos se laguea o al jugar en modo ventana y al iniciar/terminar un juego vuelve a ponerse en pantalla completa). El juego es una dinámica de perder-aprender. Al principio no lo veía así, pero después de jugarlo y que se me pasara el enojo definitivamente puedo recomendarlo!
La verdad tiene momentos con bastante tensión, aunque deben tener en cuenta que soy una persona que se asusta con facilidad xD ! Lo que más me gustó de este videojuego es que te da la oportunidad de jugar en 3 mapas diferente, lo cual ya lo hace genial. Otros juegos de anomalias solo te presentan un lugar en concreto , pero este conforme vas avanzando en las pruebas tendrás la oportunidad de explorar nuevos ambientes, aumentando la dificultad del juego. Sinceramente, lo recomiendo 💀
Ich mag Spiele dieser Art, gerade aus der Egoperspektive. Leider hat mich das Spiel schon von Beginn an überhaupt nicht gepackt 🫣 Was mich wirklich genervt hat bzw nervt ist die Tatsache, dass man immer komplett neu Anfangen muss, nachdem man "gestorben" ist. Hier wäre eine Rucksetzung zum jeweiligen Versuch (man hat ja pro Raum 8 Stufen zu meistern), deutlich sinnvoller. Das es nur in English ist war bzw ist absolut kein Hinderniss, denn es kommt eher auf das eigene Erinnerungsvermögen an. Schocker hat dieses Spiel durchaus. Ich werde dem Spiel aber sicherlich eine zweite Chance geben.
UPDATE : I changed to recommended as I got an explanation of what happened from the developer, but even with that, I still think that it can be confusing some times if an effect caused by a threat matches the description of an anomaly its not considered a positive. But this now falls into a category of my knowledge of the game and gameplay improvements, not in the category of an error in the game, so I must update my No to Yes which I think is the fair thing to do. Considering this is just a matter of dying many times to learn the effects and differentiate them, and Authogin , keep working and I hope my earlier 'No' did not felt aggressive, I like your games and I always try to provide my feedback to improve them. I played the Gravedigger and probably will play other games from you soon :) I was close to recommend this game but while recording the video of testing it, the room had the lights turn off, had my vision with blood veins, when the time was close half of the room turn off.. I selected YES because of this and I was killed after and the game said there was not an active anomaly. I played the video again to double check if the question was different and that was the trick but no, the question was the same and it was asking if there was any light changes, or effects in the vision. I will update this comment when the video is uploaded in case the developer want to check it. I'm happy to update this is I misunderstood something but I think blood veins and lights turning off its a change. Apart from that last disappointing moment the game has really great potential, performance is very good, music, audio and graphics are great, but I cannot recommend it yet if the main point of the game can break your game and kill you for example when you are going to complete the 8th room and has a mistake .
The Anomaly Experiment ~ I Don’t Even Like Horror Games, But This One Hooked Me I don’t usually play horror games. They mess with me too much. But The Anomaly Experiment really pulled me in. I was genuinely tense the whole time, jumping more than I’d like to admit, yet I kept playing because I had to know what came next. You’re placed in this creepy drug trial scenario where you need to spot anomalies — strange little changes in the environment — and missing them can have... consequences. The atmosphere is unsettling in the best way, and the puzzles are surprisingly clever. The more you play, the more immersive (and weirdly personal) it starts to feel. I’ve followed this dev for a while, and you can see how much creativity and care went into the design. The attention to detail stands out, especially in things like the second room and that TV screen. ;) Even as someone who usually avoids horror, I stuck with it because the experience is just that well crafted. There's a standard mode if you want something manageable and a hard mode if you're ready for a real challenge. If you're into psychological horror, clever mechanics, and eerie vibes or even if you're not but want to try something different. The Anomaly Experiment is absolutely worth checking out.
Ograłam ją na streamku, bardzo ciekawa, chętnie zagram w nią jeszcze raz ( twitch.tv/kitsunetsuyu )
A spot the difference anomaly game with the twist of walking through the environment, and not seeing it through screens. [spoiler] Alsooooo...With the added spice of threats possibly being there! [/spoiler] This game is beautifully well done, and has the expected quality of all other games released by this dev. Heckin' wonderful. This game was more engaging for me than typical spot the difference games. I felt more immersed into the game as opposed if it was through screens "safe away from the anomalies". I'm excited to see the future updates of this game, (maybe more anomalies?) and more quality indie releases from this dev!
Authogin rocks. i love your games so much. I cant seem to defeat the Manakins though. RAWR XD
