  • Beautiful and immersive visuals, sound design, and storytelling create a unique musical theater-style rhythm game experience.
  • Engaging and emotionally impactful story with expressive 2D art and fully voiced characters.
  • Accessible gameplay with gentle difficulty, making it suitable for casual play and story enjoyment.
  • Free Play mode feels lacking compared to story mode, with simpler and less dynamic gameplay elements.
  • Story mode is currently short with only 5 chapters, and difficulty options in the main story are limited to easy.
  • Lack of features such as controller support and retry options during campaign stages.

  • story

    The story is a beautifully crafted, stage play-inspired narrative combining visual novel dialogue with rhythm gameplay, delivering an emotionally impactful and immersive experience. It features gentle difficulty that encourages savoring the visuals, music, and storytelling, with branching paths and thematic dark-fantasy elements. Although only partly released, the story has been praised for its cohesion and emotional depth, with players hoping for harder difficulty options integrated into the story mode itself.

    • “The story branches based on choices and performance quality, as two girls move through a mysterious theater world where hope and unease intermingle while gradually regaining their memories.”
    • “The plot is delivered in visual novel style dialogue as well as the events of the plays themselves, and despite a few odd translations in English, the writing, soundtrack and illustrations combined for a very enjoyable experience.”
    • “Absolutely amazing game, beautiful songs and an emotional story that made me tear up a bit.”
    • “The story is only half done (only 5 out of what seems to be 10 planned plays are available), yet what we have so far is pretty good and hits extremely hard emotionally.”
    • “Since we currently only have one linear snippet, I can't comment on the story as a whole nor the impact of any future branching paths.”
    • “The story mode difficulties are a little on the easy side, but you can play them plus a multitude of others in free play at harder difficulties; honestly, the easy mode is nice for your first run through since you could/should be more focused on the music and level design anyway.”

  • music

    16 mentions Positive Neutral Negative
    19% positive mentions, 62% neutral mentions, 19% negative mentions

    The music in the game is highly praised for its immersive and well-crafted soundtrack that enhances the theatrical atmosphere, combining rhythm gameplay with musical theater elements. Songs are beautifully composed and emotionally impactful, with story mode offering a more accessible experience and free play providing harder difficulties for greater challenge. Overall, the soundtrack’s integration with narrative and stage design creates a unique and enjoyable musical rhythm adventure.

    • “The brisk tempo as a runner and the immersive sense of singing and acting as a musical connect naturally, creating a unique feel in which you experience a theater-style fantasy through rhythm inputs.”
    • “This game has a very cute theme around it, the early access release features 5 acts to play through and in each of them you can tell how much care was put into the stage and song designs.”
    • “Absolutely amazing game, beautiful songs and an emotional story that made me tear up a bit.”
    • “Songs in free play are focused on aleph sections only, which makes them feel a bit empty compared to songs in the story.”
    • “I would love to see songs in free play also receive their own liora sections as well!”
    • “And if possible, please make it so that story songs can also receive higher difficulties!”

  • gameplay

    7 mentions Positive Neutral Negative

    The gameplay is simple and primarily focuses on two key inputs, serving more as a backdrop to the stage plays and story rather than standing out on its own. Although free play is available, the core gameplay experience is relatively short and somewhat overshadowed by better alternatives like Muse Dash. However, the game shows potential with cohesive aesthetics and an engaging vibe that enhances the overall experience.

    • “Gameplay is simple with only two keys (high and low notes), it's technically serviceable but mostly takes a back seat to deliver the stage plays and story.”
    • “Mechanically, it's like Muse Dash, but unlike Muse Dash, the aesthetics of Nientum are cohesive and the vibes are totally immaculate.”
    • “Gameplay is simple with only two keys (high and low notes); it's technically serviceable but mostly takes a back seat to deliver the stage plays and story.”
    • “Free play is available but on pure gameplay merit there are better alternatives.”
    • “At the time of writing there are 5 chapters, totaling a little over 2 hours of gameplay.”

  • optimization

    4 mentions Positive Neutral Negative
    75% positive mentions, 25% neutral mentions, 0% negative mentions

    The optimization allows for smooth, immediate feedback during performances with intuitive timing inputs, enhancing the immersive experience. However, while the base gameplay is well-optimized, users desire additional features like a harder difficulty mode to increase replay value.

    • “The results are immediately reflected onstage, forming a structure in which you support the performance of a girl who sings while acting through timing inputs.”
    • “2 keys will be the primary form as 1 key is usually reserved for the more dramatic or climactic parts of the performance.”
    • “You can still replay the story performances themselves, but my current want is that they add a hard mode to the story.”

  • graphics

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

    The graphics are highly immersive and visually stunning, featuring cohesive aesthetics that enhance the overall storytelling and vibe, making it one of the most beautiful rhythm games experienced.

    • “Possibly the most immersive and beautiful rhythm game I have ever played thus far, in visuals, storytelling, and sound.”
    • “Mechanically, it's Muse Dash, but unlike MD, the aesthetics of Nientum are cohesive and the vibes are totally immaculate.”

  • emotional

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

    The game delivers a powerful emotional experience through its compelling story and beautiful music, with the available content already making a strong impact despite only being half complete. Players have noted that the narrative is deeply moving and evocative.

    • “Story is only half done (only 5 out of what seems to be 10 planned plays are available) yet what we have so far is pretty good and hits extremely hard emotionally.”
    • “Absolutely amazing game, beautiful songs and an emotional story that made me tear up a bit.”

  • atmosphere

    The atmosphere is richly enhanced by charming 2D art, expressive facial animations, full voice acting, and a captivating musical score, creating an engaging and immersive experience.

    • “The 2D art in cutscenes is extremely cute, the facial acting is expressive, and the fully voiced interactions and musical presentation further enhance the atmosphere of the stage.”
