Just in case somebody is wondering how to get that "ending" and doesn't know how the 4 teleports are:
- 8th floor right, say no to the creepy boy
- 6th floor left, go inside the creepy woman house
-5th floor right, leave the food and then peek through the door
-4th floor right, stay in front of the open door after you call out.
If any of the floors number is wrong let me know, I am doing this by heart so I may have mistaken any of them.
