This was an odd one. It almost managed to capture my imagination with its sparse descriptions and limited scenery, but there was still something missing. Maybe the vast number of rooms and large amounts of cycling dialogue made it tempting to start skimming and miss out on some of the setting. I think this is a game played for other reasons than immersion.
I played this as my third parser game -- although with just four cardinal directions and two other actions (wait and status) it doesn't strictly need parser input. I really appreciate the way this game streamlines and automates the parser gameplay to the point where almost all actions happen automatically. And it still manages to set up some good puzzles!
I played this on a phone with the auto-map. In hindsight, I think it would have been a better experience with pen-and-paper mapping. With the auto-map, it was easy for someone with my lack of willpower to thrust through to every unexplored room, missing subtle cues and geographical hints along the way.
I definitely think you should play this one, because it extracts one of the cores of parser gameplay while peeling a way a lot of other things. It's a fun puzzle, but perhaps even more interesting as a very well executed abstraction.
