Since you’re ok with horror, I highly recommend both Detention and Devotion by Red Candle Games. Both of them start out as horror, then gut punch you as you realize what’s going on. Devotion is an amazing example of domestic horror (the horror that can happen inside the home), and Detention is the horror that people do when they don’t realize the consequences of their actions. Devotion has stuck with me, and to this day the last line makes me want to cry.
