  • Rich and intriguing storyline presented in a comic-style format that expands on the series' narrative and adds depth to the characters and world.
  • Includes additional content like mini-games, side tasks, and replayable levels; good value and many players found it to be a significant improvement over predecessors.
  • The story and dialogue can feel overlong, sometimes distracting from gameplay; some players found the plot to be convoluted or unsatisfying with a disappointing ending.
  • Certain puzzles and new gameplay mechanics suffer from clunky controls, occasional bugs, and unintuitive design that can frustrate players.

  • story

    126 mentions Positive Neutral Negative
    38% positive mentions, 56% neutral mentions, 6% negative mentions

    The story is generally more developed and extensive than in previous installments, featuring a paranormal thriller with noir and sci-fi elements told through comic-style cutscenes. While many praise its engaging plot, twists, and cooperative character interactions, some find the narrative inconsistent, overly long, or unfocused, occasionally detracting from gameplay. Overall, the story adds meaningful depth and motivation but may not appeal equally to all players due to pacing and tonal shifts.

    • “A lot more story to this one as well, with lots of twists and unexpected turns.”
    • “The story casts players as two detectives who awaken in separate locations after being abducted by a sadistic mastermind known as the cryptic killer.”
    • “Dual perspective and a rich story line make the game feel special and new instead of a repeat of familiar puzzles and clues.”
    • “The game felt like a visual novel with lots of long and honestly boring exposition for a story that most players simply won't care about.”
    • “Their last two games were great but this one just has way too much story, lore, dialogue, and cutscenes, and unfortunately it's not very good at any of those things.”
    • “The story was confusing every single step of the way.”

  • gameplay

    57 mentions Positive Neutral Negative
    32% positive mentions, 63% neutral mentions, 5% negative mentions

    The gameplay of the game is praised for its diverse and fresh puzzle mechanics, particularly in co-op mode that emphasizes communication and parallel perspectives. While many find the variety and integration of new mechanics engaging and challenging, others note inconsistent quality, some frustrating controls, occasional bugs, and abrupt shifts in gameplay style that can disrupt immersion. Overall, it is regarded as an enjoyable experience with interesting puzzle designs, though certain elements could benefit from refinement and better cohesion.

    • “Parallel Experiment is my first Eleven Puzzles game and it feels like such a breath of fresh air; synchronous co-op gameplay and visuals, intriguing premise, and a large variety of puzzle situations that draw from various fields.”
    • “Every mechanic, narrative beat, and challenge reinforces the concept of parallel perspectives, making it feel less like a traditional puzzle game and more like a digital escape room crafted specifically for two minds working in tandem.”
    • “Having played the entire series, I can say Parallel Experiment is a good continuation of what makes these games special, with a lovingly crafted art style and a pleasant yet challenging gameplay experience that feels both familiar and fresh.”
    • “Just a few examples: the gear puzzle where you have to move tiles but it's way too laborious and there's always something in the way; a door which you repeatedly need to open for your partner by precisely and consistently circling your mouse; or a side-scrolling passage requiring you to move carts and to position mirrors but god forbid if you don't obey the clickety mechanics down to the letter.”
    • “It's a decent point and click game, several bugs and frustrating mechanics (things not clicking into place or moving somewhere else entirely once set down) make it a not so fun experience from mine and my duo's point of view.”
    • “Many times there was a brand new mechanic introduced and then never touched upon again and it shows a lack of understanding good game design.”

  • graphics

    16 mentions Positive Neutral Negative
    44% positive mentions, 43% neutral mentions, 13% negative mentions

    The graphics receive praise for their unique, charming, and comic-book-inspired art style that effectively complements the gameplay and story. While generally described as visually appealing and cohesive, a few users find the art style less impressive or not flashy. Overall, the visuals enhance the game's immersive and enjoyable experience without overshadowing the strong puzzle design.

    • “The presentation complements the gameplay with a distinctive comic-book-inspired art style.”
    • “The art style and the characters and the events are all beautifully cohesive and it also enhances communication between friends along with all the fun chaotic energy that happens among them.”
    • “Having played the entire series, I can say Parallel Experiment is a good continuation of what makes these games special, with a lovingly crafted art style and a pleasant yet challenging gameplay experience that feels both familiar and fresh.”
    • “The artstyle is meh.”
    • “The controls are a bit annoying sometimes and graphics are not flashy, but the gameplay and the puzzles are top level.”

  • grinding

    6 mentions Positive Neutral Negative
    0% positive mentions, 0% neutral mentions, 100% negative mentions

    Grinding in the game is often described as tedious and frustrating, with repetitive tasks and buggy mini-games that disrupt the flow. While puzzles are generally enjoyable, some sections feel more like endurance tests than brain challenges, lacking helpful hints and clarity.

    • “There are also a lot of just annoying grindy parts that aren't really testing your brain but just your willpower to keep doing repetitive things (like the whole elevator section in the last chapter).”
    • “It's not just this unnecessary addendum to each logic chain that makes things annoying, but also often tedious controls that make situations more difficult than they need to be.”
    • “There were several puzzles I really enjoyed, but the game lacked flow and had too many moments that felt tedious and frustrating.”

  • humor

    4 mentions Positive Neutral Negative
    100% positive mentions, 0% neutral mentions, 0% negative mentions

    The humor in the game is praised for its unexpected and lighthearted moments, such as amusing character dialogue and quirky gameplay mechanics like the sudden mini-game. These elements add personality and levity, enhancing player enjoyment even during challenging segments.

    • “Laughed so much at the parrot for no reason but it was hilarious, gonna keep an eye out for more from these devs!”
    • “Dialogue between characters adds personality and occasionally humor, helping to lighten the mood during particularly challenging sequences.”
    • “The random hard transitions in style of gameplay were jarring and the final bracing of yourself mini game was hilarious because it was a whole new mechanic (despite how basic it was) that came out of nowhere with no real reason.”

  • replayability

    4 mentions Positive Neutral Negative
    50% positive mentions, 0% neutral mentions, 50% negative mentions

    Replayability in this game is limited, especially after puzzles are solved or when playing repeatedly with the same partner, as the experience is tightly structured. While the story offers a compelling one-time playthrough, some levels can be revisited by selecting different locations on the map.

    • “Each level is replayable by choosing a location from the map.”
    • “I think it's a great game, where you won't find a very replayable story to unfold, but a one-time experience that will pull you in if you play with a good friend.”
    • “This game also lacks replayability, unlike the first two.”
    • “Because the experience is tightly structured around two-player progression, replay value is limited once puzzles are solved, especially if returning with the same partner.”

  • optimization

    3 mentions Positive Neutral Negative
    0% positive mentions, 33% neutral mentions, 67% negative mentions

    The game offers enjoyable discovery and collaboration but suffers from performance issues and less-than-ideal control optimization, detracting slightly from the overall experience.

    • “My only complaint is the performance of the game.”
    • “Just like the previous games of Eleven Puzzles, it's a lot of fun, even though the controls at some points were not really optimized.”

  • stability

    3 mentions Positive Neutral Negative
    0% positive mentions, 0% neutral mentions, 100% negative mentions

    The game exhibits some bugs and clunky elements, particularly in mini games and multiplayer NPC interactions, but overall remains enjoyable and shows promise from the developers.

    • “Some of it is a bit clunky or buggy, but the devs deserve love for this project.”
    • “- tedious, buggy mini games no one asked for”
    • “Although talking to NPCs with my other player was a little buggy sometimes (possibly due to high ping between us), this game was incredibly fun to play and the puzzles were a blast to solve, alongside the secret hunting.”

  • atmosphere

    1 mentions Positive Neutral Negative
    100% positive mentions, 0% neutral mentions, 0% negative mentions

    The atmosphere is well-crafted, with audio design that enhances the experience subtly without becoming overpowering.

    • “Audio design supports the atmosphere without overwhelming it.”

  • music

    1 mentions Positive Neutral Negative
    100% positive mentions, 0% neutral mentions, 0% negative mentions

    The music effectively enhances moments of tension and revelation, complementing the gameplay, while sound effects offer clear and helpful feedback during player interactions.

    • “Music underscores moments of tension and revelation, while sound effects provide helpful feedback during interactions.”

  • character development

    1 mentions Positive Neutral Negative
    0% positive mentions, 100% neutral mentions, 0% negative mentions

    Character development includes some highlight moments, but is generally undermined by weak voice acting, unimpressive character design, and certain puzzle elements.
