Suspenseful, eerie and a little confusing - decent game.
I was really impressed with the level of detail and how the game showcased this strangely familiar place - the beach. It had a scale and never felt like a small level in the game. The sound design was good, I liked the interactions and the puzzle towards the end. My only complaint about it would be that the ending didn't connect - the story was a bit too ambiguous and I never felt like I had to make a definitive decision. As well as small issues in the game like the metal detector going crazy for some reason and during one of the cutscenes I think the camera was way off the focus.
Overall, recommend checking this one out and finding all the endings. Best of luck with the future games!
(In all fairness, I did compare this to your previous game called "Overnight Camping" - now that one was better, in my opinion)
