Beautiful game. I felt the loss. The imagery of the room shrinking until it was solely a tunnel that the main character had to walk through was very poignant. And also the conversation with the observer (the player) that went throughout the entire narrative was very impactful. One thing that might be worth adding is walls above the intended route for the sprite. As to insure that the player can't 'fly' around the screen (Although, it is a cool motif to include in a game like this somewhere).
