Eleven Puzzles

Parallel Experiment is a two-player cooperative puzzle adventure with escape-room ideas and a noir comic-book story. You and a partner play detectives Ally and Old Dog, each viewing different clues as you chase the Cryptic Killer through a dangerous experiment. Talk through codes, locks, passwords, mini-games, and environmental puzzles so one player’s discovery unlocks the other’s next step. The Android game also offers illustrated cutscenes, optional challenges, a map-driven investigation, and a notebook for marking clues. It suits friends who enjoy communication-heavy mysteries and shared problem solving.
