This is properly spooky and that's not easy to pull off. Really well laid out with beautiful imagery too. I love that so much is packed into a small space and how it's like a temporal hex crawl where the passing of time keeps the events moving while the players are stuck inside the lighthouse with crazy NPCs (I'm also a big fan of lighthouses and we don't see them enough in TTRPGs). This would work as an awesome one-shot or side adventure in a campaign too.
