Can't get more classic than the awake in a room subgenre for a room escape game. This is well-rounded for an adventure game. You got the most important aspects nailed: have a strange atmosphere, multiple endings, and interesting pieces of text that punctuate the scene. The prose is neatly comic: I liked the deconstruction of the room escape upon discovering outside lies an emptiness of which many never return. I suppose deep down we all want to escape, but few of us truly understand what we want to escape to. Now that's existential.
