Wow, this was excellent. To come up with a story like this that doesn't feel trite is impressive on its own, let alone within 48 hours. I weirdly really liked the lack of music and sound. It made the whole thing feel a little surreal, which really matched the tone of the game.
The only thing I might have done differently was [SPOILER] actually have the door open at the end. I think a visual representation is often more powerful than being told something. One of my favorite games I've played this jam, though.
