Closed pre-alpha

Inner Datum

A co-op turn-based roguelike that runs inside a Discord voice call — and the turn waits for everyone.

Your friends are already in the voice call. Somebody starts it, everyone else clicks in, and a rain-soaked clerical city appears on a board you are all looking at. It is a city with a records system that overwrites people, and four of you in a call deciding what to do about it.

Then the turn stops. It stops for all of you.

Inner Datum resolves a turn only once every player who owes a decision has made one. So the second before a door opens is not four people mashing keys — it is a conversation. Don't open it yet. I'm at four resolve and I want the doorway. Nobody watches a spinner while somebody else's animation plays. The pause is the game.

And then it goes wrong. Somebody drops to zero and they are not dead and not removed — they are Downed, prone on the tile they fell on, with a five-turn countdown everybody can see. It turns "I died" into "get to me". Any ally who reaches them spends their whole turn standing them back up at a quarter health. If the countdown runs out they are Erased: still on the map, no longer revivable.

It is not fast. The skill is tactical positioning and cooldown sequencing, not reflexes. It is built for one specific situation: friends already sitting in the same voice channel, one evening at a time.

What makes it interesting

Where it is

Inner Datum is playable, and fewer than ten people play it. There are no releases and no hosted instance — it runs locally for a small closed group while the setting and the systems settle. There is nothing to sign up to yet.

Open source, with reservations. The game's code is published under the GPL 3.0 because it began as a partial source port of the T‑Engine4 roguelike engine, and that licence travels with it. The artwork, the setting and its prose are first-party and are not part of that grant. Source on GitHub · Credits
