Subsurface Circular
You are a robot detective who never leaves his seat on a robot-only subway, solving disappearances by talking.
Eight published games by Bithell Games where you solve puzzles, lead stealth runs, and guide small groups through strange systems.
These eight titles published by Bithell Games favor clear rules and careful thinking over fast reflexes. In Thomas Was Alone you move distinct shapes so their abilities cover each other across linked chambers, while Subsurface Circular and Quarantine Circular center on conversations where you ask questions and decide how to respond. The Banished Vault extends the same focus to planning routes and supplies across harsh star systems, so you are always weighing limited options and living with the outcome.
