About this game

“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.
*We recommend playing while wearing earphones or headphones.

◆ 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...

Boring game. You literally do nothing in terms of skill. It's beautiful. It doesn't feel exploitative. But the game is simply boring. You sit there and watch the pretty pictures bend and fold. But after the tenth time it's just repetitive. The voices and characters are great. But the game as far as being a game, is just boring. It has everything but gameplay.

Fantastic art, great soundtracks, interesting character stories! The acquirement of certain resources is a bit slow, but there is no restriction on energy or stamina or whatever, and you can play as soon as resources gather and as much as you feel like! It's my top Gatcha game, and also my favorite idle game. (Game is a niche tho, requires a certain type of person to enjoy it)

Great graphic and simple game. I have been playing for a long time now and I love the game. I would like memento Mori to improve the gacha system though. Can I suggest bank of innovation create like a story or anime like cutscene for this game. Maybe you guys can make an open world RPG of memento Mori too. can you give us platform for survey. i have some ideas for character and abilities.
