I'm not going to lie, I am dreadful at knowing what things mean, so I had to Google SoL x3 It told me that it's slice of life, so if that's correct, then yeah, I'm not really into that much as a genre >.< I was fine with it back when I first discovered VNs, but I quickly lost interest once I began to find VNs with darker sorta themes, haha. Psychological horror is probably my all-time favourite genre in gaming and films :3 I love the sorta stuff that's really creepy and disturbing without necessarily being super gory or graphic!
Well, this certainly has horror elements, hehe. I suppose most of my games do really! I don't know if what's in this will be the sort to scratch your itch with what you're looking for, but I hope you end up having fun if you do decide to play through this :3
I haven't had a chance to check any of them out yet because I'm still recovering from working my ass off for the jam, but I imagine that there are now a whole bunch of new and awesome VNs on itch with horror elements thanks to this year's Spooktober VN Jam just finishing :D
