About
“All roads lead to our ‘Goodbye.’”
Boasting an epic soundtrack that can turn the world of gaming on its head, and some of the most stunning designs ever seen in a game, Bank of Innovation’s newest title, MementoMori, is finally here!
Songs performed by many renowned artists enhance the rich world of MementoMori.

◆ STORY:
A tale of “justice” woven by girls whose fragile hearts verge on shattering...
There are girls who many call “witches.”
Although they themselves are ordinary, they can wield slightly extraordinary powers.
However, when calamity spreads throughout the land, witches begin to be feared and detested.
Before long, the Church of Longinus commenced what would be known as “The Witch Hunt.”
“Witches are to blame for this calamity. If we kill them, then the calamity will vanish along with them!”
Witches are executed one by one.
But one day, as madness seizes control of the world, it is suddenly overrun by “Curses.”
A country incinerated by hellfire. A kingdom consumed by crystals. An empire purged by the Tree of Life.
Such are the woeful desires of those who are called “Witches of Qlipha.”
Without any means to defend themselves, nation after nation falls into ruin, until finally—
The fractured land is sent adrift high into the sky.
Meanwhile, the people have yet to take notice.
From within these girls cursed to be witches, there emanates glimmers of hope.
In order to save their decimated world, these girls set forth liberating the land from darkness.
For they believe that it is the right thing to do...

Les musiques dans ce jeux sont tous simplement incroyable, j'adore trop ces musiques, niveau personnages, il y a une bonne variété et la particularité c'est que chaque personnage à une musique qui lui est propre, donc très bon concept. Il y a plusieurs point aussi qui vont pas, notamment la quantité des kindling orb, les orbes rouge, taux de drop trop faible, pour pouvoir monter les personnages, ensuite le système de devoir avoir plusieurs fois les doublons pour monter de niveau j'apprécie pas du tout, parce que déjà c'est difficile d'avoir des personnages SSR puisque les taux de drop sont vraiment bas et en plus il faut en avoir plusieurs, le coût des lotteries sont aussi cher, 3000 cristaux, avec un drop quotidien via les quêtes quotidienne de 120 cristaux. Même en 1 semaine c'est pas suffisant.
This game is "meh" not much gameplay and mostly just waiting for gaining XP so yeah. Then upgrading stuff and the "gameplay" is mostly upgrading your units and upgrading non-rare units and non-super rare units is useless, feckless. An interesting study; good sound design, good music and voice acting. The writing is alright.
1つ、ポイ活系のアプリを経由してプレイするとスタートダッシュの課金がほぼほぼキャッシュバックされ、数千円分のポイントを得る事ができます。 2つ、スマホで流れる広告が殆どこのゲームのものになり、不快な広告を見なくて済むようになります。 3つ、皆さんも既に仰っている通り、美麗な音楽とアートワークを楽しむ事ができます。 まあ、裏を返すと敢えてスマホ版ではなくこちらのSteam版を選ぶ理由はまあないって事なのですが……
lowk. peak game ever
the music is quite good. the gameplay is designed for whales, but the game is still very enjoyable for f2p people. at the very least, it could be used as a music player for the ingame superb songs while playing other games.
Can't truly recommend this - though the art, animations and music are as stunning as I remember when I last played this on mobile. I ultimately quit the mobile version, just as I have no real interest in continuing the PC version, because it just feels like a standard "red-dot" gacha otherwise. Most of my time was spent clicking on the red notification dots that popped up in a hundred places, including the index of characters, each of which has several "memory" stories that have to be individually downloaded every. single. time. Also, why is something as simple as the settings locked until stage 1.12? I couldn't even resize the window until I made it through the hand-holding tutorial and the required number of stages. And the rest of the menu/tab options are similarly locked until specific stages. This wouldn't be a problem for me since I've played a lot of gacha games with a similar design, but there are WAY too many locked menu options in this particular game. In a strange way though, this game made me nostalgic for Soul Tide which has been discontinued since 2025 and was actually engaging - I haven't encountered another game with puzzle stages like that one and miss them dearly. Even Illusion Connect wasn't half bad and had THE BEST music and visuals. RIP, bring back the fantasy gacha games that weren't just cookie-cutter menu tab collections and actually made me feel something.
