Amazing game I had soo much fun. ^-^

In case it will help someone I'll post here what i did before ED 14 activated for me. 

When I got the ED 1 I had total of 11 endings. Then i returned for the rest (this time i skipped most of the puzzles since I wrote everything down) and got ED 4 And 13 and closed the game. Then I realized that there is in fact 15 endings and got ED 9 and ED 14 just triggered.

You can turn around only when you're looking down in the elevator (before you actually look into room, it's the screen that shows up first when you change the floor) you can get back there by clicking on the green door icon in down right corner
