There is a genuine reason that this page is given a warning when you first open it up. Horror games usually end up trying to shock or scare, but eventually you come down from an intended chemical rush. This is not that.
ProtoViolence is genuinely horrifying in the events that transpire. Whether it's something more obviously graphic or a banal reality that exists today, there are subjects in here that should give you pause.
I highly urge everyone to experience it.
