Hi,
I don't know if this has been mentioned anywhere else, I couldn't find it via the search function.
Are you able to play a bomberman game with your friends? I tried it with three others, one friend and me were in the same FFA game, the others somewhere else. We waited a while for a guild game, but nothing happened. When we went to FFA, it wasn't much fun with all the rubberbanding, bad hit detection, walkable bombs (or not) and general chaos. But if we were able to play, say, a 4 person FFA with all of us in the same game, we might try it again.
There's no way to join a game with friends. Only with guild members (though good luck with that). :p
They do need to add a friend or party option. Let people group up with their friends, and all join together.
