Several people have contacted us and reported that they cannot connect through the internet.
It seems that the (poorly documented) library we used to make the networking portion of the game doesn't handle NAT punchthrough natively, meaning that if the host is behind a router, the connection will fail.
This means that the host will have to configure their router to forward the port to the internal IP address in order for the game to connect properly.
We are working on solving this issue.
If you don't want to configure the router (or if that for some reason doesn't work) you can use a program like Evolve (

to create a virtual private network. That will take care of this issue.

We want to stress that this is a workaround to the problem, and not a permanent solution!
