For pixelated Souls like games Blasphemous is an awesome one. The mysterious medieval aesthetic and the boss fights are literally perfect in every aspect. The game is kinda hard to play but still a good experience. The mechanics are easy tho. You should definitely check it out.
For other games, Mouthwashing, How fish are made, Yakuza and Death Stranding are really good options. Of course, there are also games like Silent Hill and Resident Evil. One game that remained embedded in my memory is the one called "What remains of Edith Finch" which is a kinda phycological horror (idk)? And also Last Ember where you play as a soul that reincarnated as a wolf and you start finding out about your past life, the civilizations back then and all that.
