I've completed this game 100% and I have to say we need more games play this this is a very amazing concept of the game and the story is absolutely wholesome we need more like this but...
I've been messing around in the game and I found out you can teleport and fall out the map when you interact with the elevator buttons and you walk straight out of the elevator when it closes and it will just teleport under the map, Yes I was able to quit to the man menu and load back and I had everything in my inventory slot. ilybm :))
