IMPORTANT: "Parallel Experiment" is a 2-player cooperative puzzle game with escape room-like elements. Each player must have their own copy on either mobile, tablet, PC or Mac (cross-platform play is supported).
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! Find the link on the side of our Steam page.
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.
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.
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!
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
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!
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.
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…
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.

Fun story and interesting puzzles. One of the duo puzzle games I liked the most.
This game and the whole franchise is amazing! I've played the last two games with my sister, and we're now playing this one. It's a very interesting and captivating story.
A slightly longer and certainly more ambitious game in the series, and I do think it suffers a bit for it. The devs get more experimental with the puzzle designs, especially towards the end. Some of these experiments are fun ideas that just work poorly in the game's engine and end up having janky controls that make them more frustrating than fun, but I'd rather a dev take some big swings that fail than simply rehash puzzles they've done before. This was still a very fun experience overall, I'd just caution players to approach the back third of the game with a bit of patience. The optional bar games/puzzles were a lot of fun, and I really enjoyed the mechanic of both players being able to choose dialogue options or wander in and out of conversation in real time. The more traditional escape room-like puzzles remain as fun as in past installments. If you've played the other games already and you're looking for more short and sweet co-op puzzles, I definitely think this one is worth...
Was lots of fun! There were a few puzzles that we weren't sure how the hell anyone figures out without looking up the answer. But overall we absolutely loved this game and are looking forward to whatever game they make next!
Good game - the first game was fantastic, albeit a little short. This one is slightly different. It leans into the story more, which is nice. The last 30/40% tail off a little, with less puzzles. I did like the perspective change, but standing on button isn't very difficult or fun. Enjoyed the game though, and look forward to anymore that come from the developers. Nice try on experimenting but the main draw of these games are the puzzles, so try not to stray too far from them!
Good
