 straywild is an early multiplayer fishing game. This alpha includes local

-discovery, and direct UDP connections. Expect rough edges and please keep a

 KNOWN ALPHA LIMITATIONS

+- Direct public sessions may fail behind restrictive NAT or carrier-grade
-  networks may prevent some players from joining.
+  networks. Player-hosted relay sessions add an extra network hop and may have

 - Multiplayer, dedicated-server deployment, UI, and balance are still alpha.
 - Some fish and character artwork remains temporary.
