A Roblox experience owned by Soniat.
Description (written by the developer; not a statement by this register)
WARNING: This horror game contains scary themes and depictions of 'going insane', that may not be suitable for everyone. Located in Forest Park, a city park in St. Louis, stands the Forest Park Sanatorium for the Mentally Ill. Some rumors have been going around that the patients there go even more insane than they were before. Could it be only a rumor, or is it something going on the inside?
