No. It's quite light, only "spooky". No jumpscares, only classic rpg maker spooks.I think the authors tried to be on the safe side with that warning, but anyway, feel free to play this anytime.
Thank you very much. I actually played the whole game before you made this comment and i must say at first, i was quite tense waiting for the jumpscares. But then i relaxed a bit, nonetheless i enjoyed the puzzles and the reveal at the end!
