    The gameplay is engaging and dynamic, featuring Doom-style weapon switching, dashing, and a time-stop mechanic that add depth and variety to each stage. Despite being unpolished and unfinished, it offers entertaining, fast-paced combat with unique character interactions and humorous elements. Some reload mechanics could slow the flow, but overall the gameplay remains enjoyable and fresh.

    • “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.”
    • “The developer has been giving consistent updates to improve not only the quality of life but the gameplay itself.”
    • “Doom-style weapon switching in a 3D environment along with the ability to dash and/or 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.”
    • “This is only really for the Fumo and the P90 since their reloads are the longest; I would love it if you could dash with an empty mag on the Fumo and it would reload, so you can really have fast gunplay. I find myself shooting a mag, dashing to avoid bullets, and then reloading, which slows the gameplay down.”

  • humor

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

    The humor in the game is characterized by its goofy, unpolished charm, featuring funny dialogues, a humorous story, and entertaining character interactions.

Overall, the humor contributes significantly to the game's enjoyable and lighthearted 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 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.”

  • music

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

    The music in the game is generally well-received for its quality and enjoyment, complementing the sound design and art. However, some users feel the soundtrack is repetitive from previous titles and occasionally mismatched with the levels. Overall, the music adds to the experience despite these minor criticisms.

    • “Overall, I can say that this is a short but enjoyable game with good art and music (wish it was longer though).”

    • “Despite glitches and bugs, it's actually fun to play.”

  • optimization

    3 mentions Positive Neutral Negative
    100% positive mentions, -67% neutral mentions, 67% negative mentions

    • “Game's performance is very meh, with constant stutter, especially visible when new enemies load into the map.”
