Thank you! I really appreciated how you took care of analyzing lore and events in the demo: the story is meant to be the biggest puzzle in the game and solving it fully will definitely require interpretation and reading between the lines.
Having said that, for obvious reasons I cant't spoil how the story will unfold, but I assure you it won't be about demonizing (or glorifying for that matter) mental illnesses.
Infact, mental illness is not even the main theme of the story.
(two additional notes: the portrait is not AI generated and Vincent gets indeed hooked on the pipe)
