No.
The only thing you need, is to be sure you don't have the firewall for outgoing connections.
Usually none has this firewall enabled.
I see much users that don't talk, or try to exit and enter at least 20 times in 20 sec.
This is not good.
Anyway, is very strange, much users talked to us, but they can't stay a lot to reach a good number of user online.
I'm working on some features to get for first, the communications without bugs.
I'm doing this way beacuse, the first release was perfect, but nobody known how to open ports on firewalls. And we want all can use it, cause it is very funny.
After this will be ok, i will add those features:
- Localization
- Game Center Nick
In this moment i uploaded a new update (will be published in 4 days), that will let us talk with more than one device from the same wi-fi.
So you can do test in LAN if you have 2 iphone/ipad/ipod/mac or with a friend.
For other questions, and suggestions please post!!
