When you arrive on a floor in a prime building in Tokyo, you're trapped in an endless array of corridors until you reach your office. To get out of this endless loop, you have to keep an eye on the changes that appear in the hallway.
Don't miss the changes that appear in the hallway leading to the office, turn back if there is an anomaly, or continue on if there is not. If you answer correctly 7 times in a row, you will be cleared.
There are about 30 anomalies. Find them all and aim for complete clearance. (The ending doesn't change) Sometimes you may come across unreal situations and paranormal phenomena...
You can see the anomalies in a list. In addition, once an anomaly has appeared, it will no longer appear, so you can see which anomalies can appear while playing. If it finds all the anomalies, it will display a message.
Regardless of whether you are an individual or a corporation, it can be distributed without permission.
