Lessons in Love isn't exactly horror, not at all actually. It's more of a psychological experience. There aren't many jumpscares per event/scene, but your mind is slowly calibrated as you play to be anxious for the next one and, worst case scenario, for the next of the fucked up secret events.
It's nice to know that this game has some spooky LiL-like vibes. I've been waiting for 1.2 since it's right around the corner to start playing, and knowing this in advance makes the wait even more worth it.
