Overview
Casey on the Case is a text-based adult horror adventure for players who want a darker, unsettling investigation story rather than a lighthearted one. The tone leans grim and psychological, with dread sitting alongside its adult content.
Story
Casey, a private detective carrying scars from her own past, takes on a case involving a string of disappearances. The trail leads to the abandoned Charles Francis psychiatric hospital, where she discovers the missing are being used in sexual and supernatural experiments. Pushing further into the hospital's secrets forces her to confront both monstrous captors and the unresolved trauma she brought with her.
Gameplay
Play unfolds through text-based narration as Casey investigates the hospital, piecing together clues about the experiments and the people trapped inside it. Choices guide how she confronts the horrors she finds, including hostile creatures and disturbing scenes tied to the facility's victims, with her own past surfacing alongside the case.
