I think others have hit on the major points I would make, but one thing i’ll add to the conversation is I would love this module to have more of a “Turn” i think you should write up a little beginning adventure where the crew get the pearl and make it to where its upon getting said pearl that Doris’s full sentience is awakened and her attempts to destroy the ship/save the pearl manifest.
that said this module has great vibes and I think with some effort could be super cool. Also bonus points for Akuma’s excellent Pixel art!
