This video serves as a more in-depth review but I really recommend you to play it by yourself.
I don't think I came in expecting having this much fun with fishing. Usually it's relegated to minigames or relaxing side activities. But Bryce Bucher managed to use that trope in such a creative manner, both mechanically and for story-telling purpose. Mysteries Under Lake Ophelia might not be a "horror game" per say but it hit the right spot with it's calming yet unsettling atmosphere. Can't help but recommend it, I had a great time.
