Overview
Prepare to be trapped in a seemingly endless Roman hall where reality itself seems to loop in Atrium Mortis.

Each wrong choice sends you back to the beginning, making every decision critical in your quest for escape. The game blends investigation with roguelite elements, ensuring that no two attempts are quite the same.
