    The gameplay features fast-paced, stylish combat with a perfect dodge mechanic and roguelite elements that blend well with the narrative, but it is often criticized for being clunky, repetitive, and lacking depth or meaningful upgrades. Players appreciate the boss design and movement mechanics yet find the combat sometimes frustrating due to unclear tutorials, wonky hitboxes, imbalanced difficulty spikes, and a punishing timer system that limits exploration. While the game shows clear passion and potential, many feel the core gameplay needs refinement and better balance to fully match the quality of its story, music, and visuals.

    • “Gameplay is pretty tight, boss mechanics are fun to learn and relatively simple once you get used to them, and the overall gameplay loop is just pretty fun to play with!”
    • “Because the roguelite gameplay elements and looping tie in beautifully with the narrative of this game, they are married together and complement each other fully and truly.”
    • “Insane amount of heart this game has, you can tell the dev team poured their every soul into it, gameplaywise feels so good and smooth coming from a hack and slash that's a roguelike; it's tailored to you whenever you discover some strategy to put it into work alongside the proper mementos/relic it gives you the satisfaction of feeling powerful.”
    • “Gameplay can get chaotically messy in later levels due to mobs of enemies and attack frequencies, leading to a lack of visual clarity in fights that can be frustrating.”
    • “The tutorials explain very little of the core game mechanics; the total amount taught in the tutorial is maybe 10% of the game mechanics, if even that.”
    • “Almost everything outside of the gameplay feels high quality, but the gameplay itself is frustrating, clunky, and ultimately not fun to play.”
  • story

    The story is widely praised for its engaging narrative, charming characters, and strong emotional moments, often drawing favorable comparisons to acclaimed titles like Nier and Yuuki Yuuna. While some find the storytelling occasionally disjointed or generic, the blend of mythological and religious themes, voice acting, and unfolding plot effectively captivates players and rewards multiple playthroughs. However, a few reviewers note limited environmental storytelling and pacing issues, with story elements sometimes feeling secondary to gameplay.

    • “The story, characters, setting, atmosphere, and soundscape are all incredible (especially if you like SMT, Nier, and/or post-Madoka magical girl themes).”
    • “I've stayed for the story and well written characters, as well as the unexpectedly iconoclastic mash of different religious and mythical themes.”
    • “The story captivated me from the moment the intro started and they definitely put a lot of effort into the narrative.”
    • “The story was really generic and boring, and with there not being an option to skip the story elements while I just want an unlock was extremely draining.”
    • “The story of this game, past the opening cutscene, feels incredibly disjointed.”
    • “Yes, I haven't reached that far in several runs, but how can you make a story-driven game where you are not rewarded with any lore pieces and character development regardless of your success?”
  • music

    The music in the game is widely praised as exceptional and atmospheric, often described as a standout feature that deeply enhances the game's emotional impact and setting. Composed by Pretty Patterns with contributions from notable artists, the soundtrack is memorable, varied across locations, and frequently cited for its beauty and ability to captivate players. Many reviewers highlight the music as a major reason for their immersion and enjoyment, comparing its quality to well-known titles and expressing a strong desire to listen to the full OST.

    • “Seriously, Diego (aka Pretty Patterns, the same artist who arranged 'Weight of the World', composed 'End of a Life', and produced '52-Hearts') created a masterpiece of a soundtrack, and it's always good to hear Rino and Emi Evans again.”
    • “The highlight of this game is the soundtrack; the music is amazing and carries the vibes of the game hard.”
    • “There are a lot of moments where I literally just stop playing and listen to the music.”
  • graphics

    45% positive mentions, 41% neutral mentions, 14% negative mentions

    The graphics are praised for their attractive anime-inspired art style, well-designed characters, and creative visuals that evoke a nostalgic yet polished feel reminiscent of classic eras. While not considered groundbreaking or on par with AAA graphical fidelity, the visuals effectively complement the game's atmosphere and storytelling. Some minor issues like limited exploration time and occasional hitbox mismatches are noted but do not significantly detract from the overall strong aesthetic appeal.

    • “A rogue-lite action-adventure game with a flawless OST, anime inspiration, fantastic characters and interactions, moments of pure hype, and drop-dead gorgeous visuals.”
    • “The graphics in general are quite on par with triple-A games despite being a demo, and the music reminds me of Persona 5.”
    • “This game beautifully highlights the magic of the PS2 era gameplay and story but with cleaner, newer graphics.”
    • “While the general in-game graphics are not what I'd describe as 'breathtaking', they have a very fun and creative design that marries well with the occasional anime-inspired cutscene and excellent dialogue art.”
    • “Overall, the game is, again, an okay short co-op roguelite I'd recommend on sale rather than full price if you like action games with a pretty anime art style.”
    • “Aside from the usual hitboxes sometimes not matching up with the visuals, the movement feels uncontrollable.”

    Grinding is a significant part of the game, with early stages being manageable but later levels becoming tedious and time-consuming. While grinding allows for easier progression and building powerful setups, it often feels repetitive and unrewarding, especially when leveling up characters or completing achievements. Overall, the grind can diminish enjoyment, though it may appeal to fans of the genre who don't mind the repetitive nature.

    • “Leveling up characters is really grindy and often doesn't feel worth the effort.”
    • “Early game before unlocking permanent power-ups is extremely tedious and slows down progression.”
    • “Clearing mobs or minibosses can take over 20 seconds, making combat feel very tedious rather than challenging.”

Overall, the character-related aspects contribute significantly to the game's positive reception.

    • “Very fun game, great character designs, good voice acting, music is superb.”
    • “Gameplay is a bit slow on progression; however, the gameplay itself, OST, graphics, character design, and pretty much everything I can think of keep the game a strong positive even with the slower progression.”
    • “Yes, I haven't reached that far in several runs, but how can you make a story-driven game where you are not rewarded with any lore pieces and character development regardless of your success?”
    • “Gameplay is a bit slow on progression, however the gameplay feeling itself, OST, graphics, character design, and pretty much everything I can think of keep the game a strong positive even with the slower progression.”
  • optimization

    The game runs smoothly with stable performance and high frame rates even on max settings, but it suffers from hitbox issues and occasional bugs when switching characters that affect gameplay quality.

    • “Performance: I'm playing on max settings and basically have up to 120fps constantly without any drops.”
    • “Game is good but this garbage hitbox optimization is ruining the fun along with moves not working properly.”
    • “Performance wise it runs well, no stutter no lags, but there is one bug where I change to another character and the game breaks; that could use some fixing.”
    • “Performance and stuff is fine.”

Coupled with stunning art and an evocative soundtrack, it delivers a deeply immersive and emotionally satisfying experience.

    • “Hidden gem of the genre with addictive gameplay, amazing soundtrack, gorgeous characters and emotional story.”
    • “I don't think most of the story beats hit me as hard emotionally as the aforementioned inspirations did, but I was loving every moment of the characters.”

    The game’s stability is generally solid with few glitches reported, though some users feel certain features seem unfinished or require further refinement. A rare but notable glitch involves a character executing a heavy attack combo in an unintended rapid sequence during some runs.

    • “I haven't come across any glitches, but it does feel like some aspects of the game aren't quite done and need some more time in the oven to cook.”
    • “There are a few glitches I've encountered, notably one where Spika can fire off her heavy rekka (heavy ~ light ~ light ~ light) in rapid succession after only charging the first hit, which only happens in some runs and is unclear why.”
