Endings
Reputation and choices decide the end. There is no published ending list.
Updated

The ending uses your reputation and your choices. Reputation is the same number that brings non-human customers and special orders. If you have no orders, you have nothing to spend on a faction.
There is no published ending count and no flag chart. Faction names and the cast are other pages. This page does not list them.
Who farms, who keeps the sprouts, and who is still classified is the heroines page. Serving a rival group for favor is the factions page.
An ending read uses that favor plus your choices. It does not need the cast list copied here.
Blessings apply on each rewind. Oracles are a free draw, and one of those cards can force sediment. The same text tells you the whispers are not free.
Fishing can pull an Ancient God. That is a catch, not a faction. Blackjack at the Golden Cage is a side table. Save and Load are the joke backup when the hand fails. They are not an ending requirement.
Serve the faction whose order you can fill. Talk to the heroine who is already in your building. Sissi and Nene are in the workshop loop. The others are trips.
If two factions conflict, the store page calls them rivals and stops there. It does not say a maxed bar locks the others out. Watch whether the second faction's order disappears after you commit.
The launch trailer shows the barmaid, the fox in the garden, the white-haired harvest, and the god over the roofs. Those frames match the cast pitch. They do not show affinity numbers.
Raise the person you meant to raise, and keep a manual save before a choice that will not let you preview the result.
Affinity you built in the demo is gone with the save. The full game does not load that file cleanly, and the studio reply says it is not supported.
