Subsurface Circular

Subsurface Circular is a loose take on text-based adventure games, with the game presented in a three-dimensional, third-person perspective. The player controls a robot detective in a futuristic setting, tasked with solving cases aboard a subway system below a human city that ferries around other robots that serve as the workforce.
