A Third-Person Sci-Fi Horror Thriller
Step into the fractured realities of Morty's grandfather, Dr. Adrean Voss, a brilliant physicist whose experiments with dimensional spaces have torn the fabric of reality. As Morty, you’ll traverse surreal landscapes shaped by Voss’s unraveling psyche, uncovering a story where identity, loss, and obsession collide.

Multiple Endings: In the end, it all comes to a climax, will you break the paradox or become part of it?
