The performance of the game isn't that great, especially online. The graphics for the portals need to be improved, as that is what is causing most of the lag, in that the portals aren't that great in rendering each other on one side or the other on a portal anyways :/ . The laggy network connectivity for the servers it uses is also bad, aside from the fact that the game probably needs to use a different graphics engine and better programming. That's it. Solid game.
