Nice job! I agree with the others about the visuals - they definitely add to the atmosphere of the game, plus the slightly janky low-poly style definitely makes the game feel more uncanny and spooky.
The second half of the game felt really interesting, aesthetically - it felt like the player character had stumbled into a different world, which felt unnerving.
It'd be great to see this expanded - I want to know more about the world! It was slightly frustrating having to restart from the beginning each time, but you let the player skip through quickly, so it wasn't a huge problem. The ending where you stay in the lighthouse was a cool idea, and I think it would've been great with a slightly slower pace.
Overall this was really cool - I think there's something inherently creepy about CYOA games, and you definitely ramped the creepiness factor up to 11. Well done!
