I played this and I really loved this. It's unique and athmospheric and I can't say for sure why but it's somehow just right.
I might be wrong, but are we playing a guy who is deadly ill? Because if not the extreme sudden death seems a little silly. But I guess I'll find out if you continue (please do ;) ).
I just hope you don't add any action portions to it because the controls don't feel like they would lend themselves very well to that. Just grim and dark puzzling and figuring out how to live would be my absolute dream.
I also made a video about playing your game:
