Oohra — A multiplayer survival game where knowledge is the scarcest resource: you only learn what is edible by trying, and death makes you forget.
1Features
All players share one persistent world and start with no knowledge at all. Plants have no names or icons, poisoning shows up with a delay, and knowledge passes on only through a language the players build themselves from syllables. The game runs on a custom authoritative C# server with a Unity client. A closed test is in preparation.
- Hidden plant properties, discovered by trying
- Delayed poisoning with symptoms
- A syllable language whose meaning players agree on
- Tribes with shared stores
- Generations: the Ancients and the New
- Stranger tribes with their own language
- Rock carvings outlive their authors
- Unity 6 · C# · .NET 10 · LiteNetLib · xUnit
- Platforms: Linux, Windows
