MementoMori: AFKRPG

Music and melancholy set MementoMori: AFKRPG apart from most idle role-playing games. Made by Bank of Innovation, Inc., it puts heavy weight on its soundtrack, with songs by a range of artists, and the developer even suggests playing with headphones on.

The story centres on girls branded as witches: ordinary people with slightly unusual powers who become scapegoats when disaster strikes. The Church of Longinus launches a witch hunt, and then the world is overrun by Curses tied to the Witches of Qlipha, with nations burned, crystallised or consumed. The listing's AFK label signals an idle RPG in which the party keeps progressing with little input, but the description spends most of its words on this dark, emotional tale and on the character art rather than on combat systems, so the story and presentation are clearly the focus.

It holds a 4.6 average from about 94,000 ratings, with 83% five stars and 5% one star, and it has 1,000,000+ installs. There are no ads, though in-app purchases range from $0.99 to $74.99 per item. It was updated on 2026-09-08, requires Android 8.0 or later and is rated Teen. We list 22 versions, but the newest is a very large 1.3 GB download.

Players who value atmosphere, music and a tragic storyline in an idle RPG are its clear audience. Those who want detailed tactical battles, or who are short on storage, may want to look elsewhere. The absence of ads also helps keep the atmosphere intact.
