The concept and atmosphere of this game was great. I love the choice of music and the story you described. I would have like to see more in-game story though. Well done with the procedural generation, that's always tricky to get right.
The gameplay falls a little short - to be this simple I think you need something else like story or exploration to entice the player forwards. Overall though this is a good start for what I think could be a relaxing story-based game in future.
