I thought gnosia was a good game with a few things that are scary but it wasn't really "dreadful". It's for game theory freaks I think. Can't think of any switch games that are trying to scare ppl.
Paratopics good, if a bit confusing. It's got a bundle with the creators other game (i can't remember the name for the life of me rn), and it's pretty cheap! It's got a cool ps1 low-poly vibe
