You’re not going to find more text/explicit plot than you have already. That said, there is good environmental storytelling in the last zone of the game. The next zone for you (Wrecked Ship) might have a little more for you to chew on. I’d say get through that zone and then see how you feel about it. If you like it, the ending will probably feel rewarding.
Ouch. Even selling it to Fandom would have been better than this.
