I just started playing last night and streamed for a few friends who thought it looked fun, and it is. We were all on the same team but could not find a feature that allowed us to add friends. If a feature like this exists please let me know, but we could find no such thing. I would be nice if you could add friends and see them as a third color triangle. We found it was hard to sync up in battle because we had no way to indicate to one another where we were.
