  • Free to play and accessible, with potential for improvement and expansion in future updates.
  • Lack of tutorial or clear instructions makes the game confusing and harder to get into initially.
  • Voice chat is often buggy and unreliable, with players recommending third-party communication tools.
  • Bugs and glitches affect gameplay, including lobby issues, door mechanics, and matchmaking resets after rounds.

  • atmosphere

    5 mentions Positive Neutral Negative
    80% positive mentions, 20% neutral mentions, 0% negative mentions

    The game offers a fun and engaging atmosphere, especially enjoyable when played with a partner, with a strong sense of pressure and immersive ship setting. While it doesn't feature elaborate endings or surprises, its atmospheric tension and task management create an enjoyable experience.

    • “Great atmosphere, very fun.”
    • “Very fun game to play with your lover, I really enjoy the atmosphere of the ship and the juggling of tasks!”
    • “No fancy endings, no knowledge, just atmosphere and pressure.”

  • stability

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

    The game's stability is frequently criticized due to numerous bugs, including issues with voice chat, missing settings, glitches causing players to get stuck, and the need to restart after matches. While some recognize minor bugs as expected for a recent release, these issues disrupt smooth gameplay and impact overall experience.

    • “Terrible experience, the game is good and a good idea but everything is so buggy. You can't go to the lobby; you have to exit the game. After every game, you still have to restart it to make the walkie-talkies work.”
    • “In all seriousness, the voice chat was buggy, there was an incredible lack of settings, the game was very short, FPS wasn't the greatest especially for a small submarine like that, and the events were a bit boring and easy.”
    • “Had a few glitches when I loaded in: I immediately paused, and my cursor was gone. I was able to grab the ladder as a captain, trapping me out of the room. Also, the game would benefit from a short tutorial and a win/lose screen.”

  • humor

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

    The humor in the game is lighthearted and creates amusing, tense moments, especially during initial rounds when players are figuring things out. While the gameplay isn't very challenging, the funny situations and interactions keep the experience entertaining.

    • “The concept is simple, and it definitely creates some tense and funny moments.”
    • “The first couple of rounds, when we both didn't know what we were doing, was hilarious.”
    • “All in all funny, but my friend and I were too braindead to find where we needed to put the torpedoes, so we died every time.”

  • gameplay

    4 mentions Positive Neutral Negative
    50% positive mentions, -25% neutral mentions, 75% negative mentions

    The gameplay is praised for its intense, cooperative mechanics and engaging loop, though some feel it could benefit from additional content like more puzzles. While generally enjoyable and true to its promise, minor bugs are noted but expected given the game's recent release.

    • “It's free, lightweight, and delivers exactly what it promises — intense cooperative gameplay in which misunderstanding means instant death.”
    • “Great game, gameplay loop is good, slightly buggy but it came out a week ago so it's expected.”
    • “I think the engineer class could use more gameplay depth.”
    • “I'd love to see a full version of the game with more gameplay and puzzles.”
    • “Great game with a good gameplay loop, although it's slightly buggy, but that's expected since it came out a week ago.”

  • replayability

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

    The game offers limited replayability, mainly restricted to swapping roles, which may reduce long-term engagement for some players.

    • “A shame it doesn't really have replayability beyond swapping roles though.”

  • music

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

    Users appreciate the music's contribution to the game's atmosphere and suggest adding more eerie tracks in future updates to enhance intensity and variety.
