Very few things are configurable; the credits are displayed in the main menu and can't be hidden, and the data saving is terrible and crashes constantly. Support is practically nonexistent. I'm still waiting for an update to remove the credits, and it's been since October... In short, good idea, very poorly executed.

For a paid game with a limited license, it offers very little, and has errors. It doesn't show the players who are in the arena, and shows 0 even if there are players. When you want to leave, sometimes it says you're not in any FFA arena. Money wasted, but let's see what I can do because there are no refunds.
