Developer Description
Two detectives, one deadly experiment. Only together you can survive.
In the game players take on the roles of two detectives who are often separated, each with different clues, and must work together to solve puzzles. Internet connection and voice communication are essential. Need a Player Two? Join our community on Discord!
WHAT IS PARALLEL EXPERIMENT?
Parallel Experiment is a noir-inspired adventure with a comic book art style, featuring detectives Ally and Old Dog. While following the trail of the dangerous Cryptic Killer, they suddenly become his targets and are now unwilling participants in his twisted experiment.
This is the second standalone chapter in the “Cryptic Killer” cooperative point-and-click puzzle game series. You can play Unboxing the Cryptic Killer first, if you want to learn more about our detectives and their nemesis, but Parallel Experiment can be enjoyed without prior knowledge.
KEY FEATURES
🔍 Two Player Co-Op
In Parallel Experiment, players must rely on their communication skills as they’re separated and must each discover unique clues that are vital for solving puzzles on the other end. Teamwork is essential to crack the Cryptic Killer’s codes.
🧩 Challenging Collaborative Puzzles
There are over 80 puzzles striking the perfect balance between challenging yet fair. But you're not facing them on your own! Communicate with your partner on how to best proceed, solve a puzzle on your end that unlocks the next step for them and discover a wide variety of puzzles from redirecting water flows, finding computer passwords and unlocking intricate locks, to deciphering cryptic ciphers, soldering electronic components, and even waking up a drunk!
🕹️ Two Can Play That Game
Looking for a break from the main investigation? Dive into a variety of retro-inspired mini-games designed with a fresh cooperative twist. Challenge each other to darts, Three in a Row, Match Three, Claw Machine, Push and Pull, and more. Think you know these classics? We’ve reinvented them for a whole new co-op experience
🗨️ Cooperative Dialogues
Uncover vital clues through collaborative conversations. NPCs respond dynamically to each player, offering new layers of interaction that only teamwork can unravel. Some conversations are puzzles in themselves that you need to solve together!
🖼️ A story told in panels
Our love for comic books shines in Parallel Experiment. Every cutscene is presented as a beautifully crafted comic book page, immersing you in a gripping, noir-inspired narrative.
How many pages did we create to tell the story? Almost 100 pages! Even we were surprised by how much it took, but every panel was worth it to deliver a story that keeps you on edge until the very last frame.
✍️ Draw on… Everything!
Every detective needs a notebook. In Parallel Experiment, players can jot down notes, sketch solutions, and interact with the environment in creative ways. But we all know what you're going to draw first…
🐒 Annoy Each Other
This is a key feature? Yes. Yes, it is.
Each level will have some way for players to annoy their co-op partner: knock on a window to distract them, poke them, make their screens shake. You already know you'll be doing this just by reading it, right?
Parallel Experiment has a variety of mind-twisting challenges that push the boundaries of cooperative puzzle design, offering situations never seen before in other games.

Parallel Experiment users say on Google Play
The first two games were fantastic. They revolved around solving puzzles together. This game unfortunately adds a lot of new annoying mechanics, and way too many cutscenes. Also the minigames are absolutely horrible. I would suggest the devs stick to what made the first two games great.
