This post reminds me of Nemlei's games... a lot of them have really compelling themes related to traumas, such as being stuck within a corrupt and uncaring system that forces you to hurt others to survive in No-good Noelle or Divilethion, the horrors of depression in Better Half or terrible family dynamics in... almost of them really (what The Coffin of Andy and Leyley seems to be mostly about, I haven't played it yet sadly).
Anyways, I think Nemlei is a really good, but underrated vn creator, so if you're feeling like something kinda melancholy and tragic I'd recommend checking them out!
