About This Game

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.
