This is quite good and it is also free!

Get out of the building via the stairway. Observe the levels carefully for a successful exit.

If everything is consistent in the level with the baseline state, proceed.
If you observe any anomalies, turn back!


Once you're out of the building, you can start the game all over again to experience all the anomalies!

If you assume the level is an exact copy and consistent and you are wrong you will start back on the 12th floor.

There is no serious jump scares, occasionally a solid black figure will appear but it never grabs you and will just run right through you if you are in the way.

If you believe you have a great eye for detail this is quite fun!
