label principles:

Three rules everything here follows.

They are the reason the products look the way they do, and the reason some obvious features are missing on purpose.

01 — privacy

Anonymous, or it doesn't ship

No accounts, no e-mail addresses, no device fingerprints, no IP logging — not even in the proxy in front of the server. Players opt in inside your game and can withdraw at any time.

02 — scale

Built for one-person studios

Drop in a file, ship your build, read the numbers. If a feature needs a call with us to be useful, it is the wrong feature.

03 — ownership

Nothing you can't take with you

Every product runs on your own hardware from the same source we run. Your data stays a plain file you can export, move or delete.

label products:

One product so far.

Kybeia Arc is the first. What follows will obey the same three rules.

label the_name:

κυβεια — the game of dice

The ancient Greeks had a word for playing at dice: kybeia, from kybos, the cube. It is the oldest name we have for the thing every game still runs on — a set of possible outcomes and the choices that pick between them.

That is also why the mark is a cube with a branch inside it. Look at an isometric die and you are already looking at a decision tree.
