I rewrote the master server software and it is now running. Everyone should be able to use it now in the new version I just uploaded (0.1.2).
When hosting a server verify if the option “Broadcast to Master” is checked, otherwise your server will be not visible to public.
If people can see your server but can neither join or see game info, check your firewall or/and try port forwarding.
If you still have problems hosting, can’t connect to master server, or it shows wrong information, please report.

Minor changes:

• You can now choose your color at “Player Setup”;

• Players bleed for a few seconds after being hit;
