I fell asleep in a car and then arrived at a hotel which was overrun by living mermaid statues. I tried to ignore it and sleep in my room but one eventually got inside and turned me into one as well! I got the death ending. I played it a couple of times just to try different things out but arrived at the same ending.
You created a very unsettling atmosphere. The mermaid statues were simple but actually quite scary. I found it satisfying to be turned into one.
I am curious about your choice to allow the player to sleep through a lot of dialogue which sets up the story in a nice creepy way. It made my first playthrough feel like I had missed something important in retrospect. Perhaps there's could be another opportunity to learn about Siren Town once you were at the hotel? Maybe through an exchange with an employee?
