You should be fine. It’s a card game first and foremost, so no enemies sneaking up on you per se. There are some creepy things happening and, without going too much into detail, a lot of fourth-wall breaks - you’ll know when you see. That can take you by surprise a little, but if you’re fine dealing with that, you should be ok.

There can be some minor body horror involved that can be a little gross. There is one action you need to take to progress the game eventually.

Overall, it’s not full of jumpscares - it’s just scary atmosphere and creepy vibes. I myself am usually rather easily scared by video games, but I’ve been fine throughout. Give the first hour or so a try to get a good feel for it. The rest of the creepiness will unfold itself later on
