It's much maligned, but Spirit Camera: The Cursed Memoir is much better than people give it credit for.

 

Creeping Terror is only of the best, if not best, horror game on the 3DS despite what reviewers of it say. Other games I know of that are horror and can actually get scary are only two, Resident Evil: Revelations and a Japanese only game I can't remember the name of, it's one of the number series games (type "SIMPLE DL" in the search in the Japanese eshop and it's that one with the creepy mask, I think it's number 35).

 

Corpse Party isn't really "horror", it is, just not scary at all. It's made with RPG Maker, so it's not exactly too deep a game, although can be fun. It's just that it has more of a casual or kiddy vibe to it, except for all the ass comments a certain character makes about someone else's butt or her own

To give you an example of the ass comments I included some screenshots... (excuse the bitmap format, Luma screenshots)

 

But Corpse Party doesn't have jumpscares and is actually fun, so nothing like FNAF or the category of games you are referring to Still not as good as other games though, so just stick to Creeping Terror, RE:R and that other game I mentioned.

 

4 FNAFs? There's 1-5, sister location, some fan-made ones, some fan-made with official support ones, etc. resulting in almost 15! There hardly are any games that are actually horror on the 3DS unfortunately... Did you find that "SIMPLE DL" game I mentioned by any chance? I can get you exact name if you want me to, but remember, it's only in Japanese. What kind of "horror" are you looking for exactly though? Depending on that, I may be able to suggest some more for you that are close to horror.

 

You should. it's quite thrilling and scary.
