Parallel Experiment is a clever, cooperative point-and-click puzzle game built around the premise that two players-each with different clues and screens-must communicate constantly to progress. Framed as a noir-inspired detective story, it casts you and a partner as Ally and Old Dog, reluctantly caught in the Cryptic Killer’s twisted experiment. The result is an escape-room-like experience that rewards teamwork, patience, and a good headset.
