New Animations


The game now shows "conflict" animations that result in measurements of the game state. We hope this helps players understand when and why measurements occur.

Analyzing Games


After a completed match, you can now analyze the game, and explore different moves!
While spectating you can swap over to analysis mode at any time and explore different measurement outcomes! While analyzing a game, click a previous ply to explore an alternate history from that point.

Dedicated Multiplayer


Dedicated games hold and modify the state of the game on a dedicated server, instead of local machines. This sets us up for some other cool features in the future.

Local Play


Side by side let's you play against a friend on the same screen, and lays the groundwork for a re-release of an AI opponent.

We also packed in a lot of bug fixes. When you find more, be sure to let us know in our Discord!

As always, thank you for your continued support.
