Just been released recently, Corpse Factory. Released in English dubbing only but with some very good voice acting, the hook hits you pretty fast and it has lots of twists and turns. Warning for some heavy psychological themes including distressing and disturbing topics, and overall quite a morbid and disturbing story. I absolutely loved it, and I'd recommend it to anyone who enjoys psychological horror.
I like the ending that makes the story feel complete without feeling like it cheated the reader by making up random stuff or by shortcutting to get to that ending. For example (Heavy grisaia series spoilers)
