An interesting idea. The ending is absolutely brilliant.
I'm not a fan of this genre, as everything quickly becomes repetitive, even on a jam-sized scale. But, as far as I can tell, it's well done.
My only real criticism is the lack of sound. Unpacking and throwing items are silent, even though these are the most important interactions in the game.
Great work with the atmosphere and the story's theme! It's a shame the story is limited to the intro and ending, as the setting is unusual; I'd have liked some more details in between.
