Aetherium Hearts vs Demon Prince

Raise adventurers in Selwyn, town of the Ash Marches, and send them down into the labyrinths. The expedition runs by itself — they walk, they fight, they gather, and sometimes they fall. Those who come back bring the whole of it with them, written up by an AI as a single tale. No two are ever the same. ◆ Three labyrinths The Ashen Corridor, the Frostcrystal Archive, the Ember Crucible. Each runs to a different depth and a different danger, and at the bottom of each an Aetherium Heart lies sleeping. ◆ It runs on its own Once they are down there, they walk and fight on their own feet. The descent continues while the app is closed. ◆ Tales The record of a returning expedition is woven into prose by an AI. Send it straight to X, Threads, Bluesky or Discord. ◆ The town and your company An armoury, a general store, a forge, the guild, a temple, a shrine — Selwyn holds nine places to go. You can also go looking for an adventurer who has gone missing. ◆ Standings Set the Aetherium Hearts you have offered at the Shrine of Astel against every adventurer in every town. Japanese and English, switching with your device. Free to play, with no in-app purchases.

"How many steps did you take today?" Every one of them helps take back a lost kingdom. Demon Prince is a walking x idle RPG where your step count is the fuel for the adventure. Play as a prince driven out of the demon realm, gather the allies you were separated from, and win back your stolen territory one step at a time. No paid gacha. Free to play. - The world moves when you walk Every step you take in the real world earns WP (Walk Points). Pass a step milestone and a new species wakes up, ready to join you. Spend WP on the Prince's Blessings to push an expedition further. Your commute, your evening walk, the trip to the shops - all of it is more of the adventure. - Send them out, then get on with your day Expeditions advance on their own over time. Send your party out and leave it alone. The kingdom comes back to you a little at a time, in the gaps of a busy day. - Build a party that fits together A shield who takes every blow, a mage who clears a crowd at once, a healer who keeps the front line standing - every monster has a role and a character of its own, with its own skills, elements and resistances. Some monsters carry a passive that works just by being in the party - a stat raised for everyone, a resistance shored up, or one fallen ally brought back per battle. Passives from different species stack, so the lineup itself is part of the build. Battles resolve automatically, so what decides them is who you bring and how they fit together. Read who is waiting in each region, and build a party to match. - Every run is a different meeting Even in the same region, the monsters you meet change from run to run. "Who will I run into today?" There is something new every time you go out. - No gacha. The time you walked does not lie. There is no paid gacha. Strength comes from the steps you have taken and the time you spent raising your party, and from nothing else. So: walk. Every step of yours goes into rebuilding the Demon Army.
