Wait, so where was the key in that room? The one with the furniture shaped like a capital I, with some of it floating in the air.
The problem with sleeping was that, in the first room with a key, I was looking around and would fall asleep as soon as I interacted with the bed. It took me three tries to find the key hidden in the corner behind the furniture, and every time I had to restart the entire game. It wouldn’t start from the beginning; instead, it locked me on the title screen.
I really wanted to see the ending, though, because the game felt interesting. Thanks for the detailed reply, by the way.
