Unfortunately there is no "Select Chapter" mode or anything comparable in this game. So in order to get to two endings (leave or stay), you have to complete the whole game twice.

You can skip a lot of the storyline by entering the room codes directly (and not returning to other areas in order to find them).

Floor 1: 1313
Floor 2: 5382
Floor 3: 3159
Floor 4: 2021
Floor 5: 1474
