About The Mortimer Paradox
Navigate your way through the strange dimensions create by your Grandfather, and you search to find out what happened to him. Find out why the crack in reality he created may end everything. Discover why he dove deeper in, and maybe find a way back to reality for yourself.

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.
What to expect when you step through the portals...
Cinematic Third-Person Exploration: Navigate surreal environments Dr. Voss's memories bleed into reality.
Narrative-Driven Gameplay: Uncover a deeply emotional story about identity, loss, and the cost of rewriting fate. Told through pages of Voss's notebooks, environmental storytelling, and voice-over fragments.
Multiple Endings: In the end, it all comes to a climax, will you break the paradox or become part of it?
Atmospheric Music: Music by Marcin Szmuc
Stylized Visuals: A fragmented, dreamlike aesthetic that reflects the unraveling psyche of Dr. Adrean Voss.
