Powerful imagery throughout! I think your work is a good argument for interactive narratives, as they compel readers to explicitly create meaning through choices. "Is this about depression, or the after life?" and "what is the relationship between both concepts?" is what kept going through my mind. Of course, this openness of interpretation could be enhanced if the player choices produce richer outcomes. As it is now, it leads to the same (powerful) ending, so it is worth considering an expansion, IMO. If you decide to do that, let me know!
