About 15th Prison

You are stuck in a prison with endless blocks where notorious criminals are located. This is a prison famous for very horrific events.
To go to block 15 and find the escape route in the prison, observe your surroundings carefully and take the envelope given by the guard at each block pass. These envelopes are important for your escape plan!

Do not ignore any anomalies.
If you find anomalies, turn back immediately.
If you do not find anomalies, do not turn back. Move forward.

When you reach block 15, 3 different doors are waiting for you. You will encounter different endings and puzzles in these doors.
If you solve the puzzle at the end, your escape from prison will be easier. Good luck…

Decent anomaly game for the price. The difficulty feels about right, though the movement in-game is a bit janky.

This game is a nice change of pace when it comes to the anomaly spotting scene. Where every game tries to be an office, or some Japanese place to cash in on The Exit 8's success, This one gives us a different area in its entirety taking place in a prison. So I do really like that. Game is relatively short, so keep that in mind before buying it. The visuals are fine, could be better but its done fine enough. The game couldve done with more music or sound or anything. its fairly quiet. All in all, can recommend it when its on sale. If its full price, just wait a bit.

Decent anomaly game. Like nearly every other Anomaly horror game, 15th Prison suffers from the lack of what I call a "Baseline". This game, and so many others, don't have a "normal" (or baseline) level that the player can check to see what is and isn't considered an anomaly. In this game, "Block 0" should be the same layout every single time so that if you fail and get reset, you can look and compare what was or what wasn't considered an anomaly. This helps avoid confusion for the players for things that might be bugs or oversights by the dev. Such floating balls of light above jail cell doors, misplaced textures or odd geometry. The game overall was not bad, but a lot of the time I was left with a 50/50 guess because what IS and ISN'T an anomaly isn't clear most of the time. I found myself thinking "oh hey that's an anomaly!" - running backward to the door - getting the anomaly RIGHT - but then it turns out what I thought was the anomaly wasn't even changed and I just got lucky.

The game looks nice and runs well, no problem with that, but for me it was just too diffcult, but if you're an anomaly game pro you will probably like it. UPDATE: after playing it again turns out: i am just blind. there's one anomaly that really got me. i won't tell you want is thought :-)

It's one of the more difficult anomaly puzzle games with some highly effective and disturbing jumpscares, with 15 levels to complete. Recommended for every fan of the genre. 9.5/10
