    5 mentions Positive Neutral Negative

    The gameplay is engaging and offers unique depth through Doom-style weapon switching, dashing, and a timestop mechanic, making each stage feel distinct, especially during speedruns. Although some weapon reload mechanics can slow the pace, the overall experience is entertaining, goofy, and enhanced by quirky character animations and a humorous story.

    • “Doom-style weapon switching in a 3D environment along with the ability to dash and temporarily stop time adds depth to gameplay, making each stage feel unique even when speedrunning, as no battle will ever play out the same way.”
    • “Despite the fact that this game is far from a properly finished product, its gameplay is still entertaining enough to be worthy of your time.”
    • “This game shines as a goofy, unpolished game with quite entertaining gameplay and a funny story; you will see characters dance as they attack, some will fly away when shot with the triple-barrel shotgun, and others just get stuck on the ground.”
    • “Doom-style weapon switching in a 3D environment, along with the ability to dash and temporarily stop time, adds depth to gameplay, making each stage feel unique even when speedrunning, as no battle will ever play out the same way.”
    • “I would love it if you could reload the Fumo weapon by dashing with an empty magazine, as currently, shooting a mag, dashing to avoid bullets, and then reloading slows the gameplay down.”
  • humor
    4 mentions Positive Neutral Negative

    The humor in the game is characterized by goofy, unpolished elements and funny dialogues, story, and character interactions that enhance the overall entertainment. Silly visual gags and quirky mechanics contribute to its charm, making it a humorous and enjoyable experience.

    • “The dialogues are very funny, and the timestop mechanic works way better than in the prequel.”
    • “The story is funny and the interactions too, overall worth the time and price.”
    • “This game shines as a goofy unpolished game with quite the entertaining gameplay with a funny story; you will see characters dance as they attack, some will fly away when shot with the triple (yes triple) barrel shotgun, and others just get stuck on the ground.”
  • optimization
    2 mentions Positive Neutral Negative

    The game's optimization is lacking, resulting in frequent stutters, especially when new enemies appear. Performance issues detract from the experience, making it feel more like an unfinished demo than a polished game.

    • “Game's performance is very meh, with constant stutter, especially visible when new enemies load into map.”
    • “Better level design, better enemy design, improved performance optimization, I just feel what you're selling could be more of a demo of what awaits the players rather than an actual game.”
  • music
    2 mentions Positive Neutral Negative

    The music in the game is criticized for not fitting the levels well, with some users noting that the soundtrack feels reused from the first installment.

    • “Third, the music doesn't really fit the levels at all.”
    • “Soundtrack: isn't this the exact same one as the first game?”
  • story
    2 mentions Positive Neutral Negative

    The story is noted for its humor and entertaining character interactions, adding a fun and quirky charm to the game. While the game may feel unpolished, its goofy narrative and playful moments make it a worthwhile and enjoyable experience.

    • “The story is funny and the interactions too, overall worth the time and price.”
    • “This game shines as a goofy, unpolished game with quite the entertaining gameplay and a funny story. You will see characters dance as they attack, some will fly away when shot with the triple (yes, triple) barrel shotgun, and others just get stuck on the ground.”
  • grinding
    1 mentions Positive Neutral Negative

    The developer has been steadily improving the game over time, addressing grinding-related issues, making it more enjoyable. However, users suggest purchasing it on sale due to lingering drawbacks.

  • graphics
    1 mentions Positive Neutral Negative

    The graphics are generally well-received, avoiding excessive or unpleasant effects that could detract from the visual experience.

  • stability
    1 mentions Positive Neutral Negative

    The game’s stability is hindered by bugs, particularly on the third map where players frequently get stuck inside rocks, disrupting gameplay.

    • “The third map is so buggy that I spend more time stuck inside a rock than actually playing on it.”
