My name is HSelf. I am a writer and a solo Visual Novels developer. I have released a handful of visual novels on Steam in the past. I’m a writer and not an illustrator, which means I often rely on multiple artists in order to develop my games. As such, since there are bound to be some unpredictable variables, I can’t promise any kind of timeframe for any new release. Still, I’ll try my best to release new updates every month.

    I have a hard time playing these games because I just hate the antagonists face. I can’t stand looking at him. I just want to smash his face in until he swallows his own face.
