If you’re a fan of anomaly games, you’ll be instantly familiar with the mechanics. But for newcomers stepping into the darkness for the first time, the rules are mercifully simple. Your task is to reach floor 1 by keenly observing anomalies and making the right choices. The setting is deceptively minimalist: a grimy, dimly-lit staircase landing with a table littered with cards, scattered junk, and little else. Your journey begins on the first floor, and each subsequent “loop” has to mirror the original scene with perfect precision. When everything looks as it should, you progress downward. But if something is even slightly off, you need to go back the way you came. Anomalies come in all shapes and sizes—some glaringly obvious, others maddeningly subtle. Sure, there are straightforward clues like a flickering light or a misplaced object, but the real challenge lies in spotting the nearly imperceptible ones. A tiny peephole beneath the table, for instance, can easily be missed if you’re not examining every corner with obsessive focus. In my experience, the most effective strategy was simply to keep looping until the more apparent anomalies made themselves known. But here’s where things get interesting. The first run is only the first part of the story. Once you return to the main menu and dive back in for a second attempt, you’ll find that the corridor has changed—become darker, more oppressive, with the ominous addition of a massive clock looming on the wall. And then there’s the third and final part. The location resets to its original state, but it adds two creepy children now peer from behind the two doors. These new assets bring exclusive anomalies, but most of them will show up across all three stages. One thing the game does brilliantly is respecting your time. Completing the game unlocks the option to revisit any of the three stages to hunt down those missing anomalies. There’s even a handy anomaly counter for each stage, giving completionists something to aim for without the frustration of endless guesswork. Better yet, the game prioritizes undiscovered anomalies, ensuring you’re not just grinding through them to reach that final achievement.
Another "if you see an anomaly, turn around and go back" style game. Some of the anomalies are hard to spot, and I haven't gotten all of the endings, but it was fun. A couple of the anomalies made me laugh, and I thought the way the stairs worked so you were always going "down" was really well done.
I had so much fun playing this game. I love "find the difference" games and making it into the horror genre was a great idea. I also like that it has multiple endings. The game is fairly easy but having multiple endings does make me want to replay it over and over again.
I received a copy of this game free, but all opinions are my own. I am not normally a horror game player but I was very pleasantly surprised to find I genuinely enjoyed this one. Gameplay is smooth, it feels really well thought out and the vibes are definitely creepy. I still want to find all the anomalies but I have had fun finding the ones I have. Some are super hard! Definitely recommend.
i enjoyed it but alittle difficult for me but thats to be expected because i have alot of trouble with anomaly games but i got all the ending

Ladies, Gentlemen, Others; do you long for a game with the ethos of Shawshank Redemption, the Pathos of Toy Story 3, and the Logos of Blackfish? Well, you've come to a place. No not a place for those. Why did you come to a anomaly game for that? Level 13 is a quintessential anomaly game from a solo dev worth your time and money. For the low low price of $3.99 (at the time of writing, tariffs pending) you too can experience not one, not two, but three anomalisa-type games. But seriously, what a solo dev has accomplished here is very fun and very worth your time. <Heart-emoji>
I head down the stairs to goww down, but going up the stairs also goes down. They're the real anomaly. For real though, i have been having a blast reactivating the 'I Spy Books' part of my brain. Maybe like 2 to 3 out of 5 spookies for me but 5 stars for the whole game for the price.
Nice anomaly game
