You are just about to move into your new apartment, unit 043. But getting to your home isn't as simple as you imagined, the path is riddled with loops upon loops of the same hallway, but are they really the same? 

Apartment 043 is a observation game aimed to test the player's memory and perception skills, not just visually but audibly. If the player decides the level is clean of any anomalies they walk through the green door. On the other hand if they find any anomolous traits within the level they will need to go through the red door. Once they correctly pick the door 6 times in a row they will then safely reach home and finish the game. If they pick incorrectly once they will be sent to a bad version of their home, where a killer awaits them on the inside.
