What it is

In two sentences

Moonfall is an AI card game you play in your browser: play a card and an AI storyteller writes what happens next. Forge new cards in the Moon Foundry, and turn your match into a manga.

Longer

Every card play is a prompt. An AI Game Master decides what each card does and tells the story of the match as it goes, so every game tells a little tale.

In the Moon Foundry, two cards become one: forge new cards and add them to your collection. With the Manga Pass, the AI inks your battle into manga pages, and your match can become a shareable storybook. Dream up your own summoners and the spells they cast in Moon Dream, collect and trade cards with other players, and find Stellar cards, living cards that move. Play solo or against friends, in your browser, with no download.

Moonfall uses AI to tell its stories, to write and paint its new cards and to ink its manga. AI output can still be imperfect.

Manga pages

Six pages from one real match, Kitsu against Einar Skjoldr, as the AI inked them with the Manga Pass. Each caption is the AI storyteller's own line from that turn. It is the match in The Moon Cracks Open.

  • A manga page in two panels: Einar Skjoldr, a blue-skinned warrior with a white beard and a fur mantle, shatters a glowing card in the mountain wind, saying “Show me the edge.”, then holds up a great ice-blue axe: “The answer is found.”
    “Show me the edge,” Einar Skjoldr rumbles. Turn 3 · 1264 × 848 JPG
  • A manga page: Einar Skjoldr drives a glowing red axe into the rock while a pale spirit, Echo Wisp, cracks apart (“…chime… s-shattering…”) and bursts into shards (“Silence.”).
    “Silence,” Einar Skjoldr rumbles. Turn 5 · 1264 × 848 JPG
  • A manga page: Mist Weaver, a spirit of mist, wraps Einar Skjoldr in fog on a cliff edge (“Lose your way in the mist.”), and he slips, losing his grip (“Agh! My grip… the world itself is against me here!”).
    “Lose your way in the mist,” Mist Weaver whispers. Turn 8 · 1264 × 848 JPG
  • A manga page: Mist Weaver pours freezing cloud into Einar Skjoldr's lungs (“Agh! My… air! The world chokes me!”), and a blue Moonbloom flower stings him with its spores (“Bloom.”).
    “Breathe it in,” Mist Weaver sighs. Turn 10 · 1264 × 848 JPG
  • A manga page at the Sky-High Aerie: a moon with tentacles glows over the mountains while Kitsu, a nine-tailed fox, says “Look up, Einar. It's all Kitsu now.”, and Einar's own warband turns its blades on him (“My… my own axe… No!”).
    “Look up,” Kitsu purrs. Turn 20 · 1264 × 848 JPG
  • A manga page: Einar Skjoldr, drawn here as a red-bearded warrior, roars “Pull it down!” as the cracked moon falls, and Kitsu the nine-tailed fox stands in a blast of silver fire.
    “Pull it down,” Einar Skjoldr roars. Turn 23 · 1264 × 848 JPG
