I honestly can't tell if it's a horror game or not TvT
I see! There are no classic jumpscares(like sudden spooky picture for the whole monitor) and/or sudden loud noises
But! There are one moment, when you should turn your camera to the left and suddenly you will see a character standing there. I wouldn't consider it for a jumpscare, but this segment might be uncomfortable for some players. So please decide what's will be best in your situation and take care!
It is absolutely fine if this will be the reason for you to not play the game. If i can help in any way possible please let me know!
