My only critic to the game development is that communication seems to be a little bit in too many places. But having said that each update has been solid and price/value(fun) the game is already great.
And yet i can't wait!!!! :P
I am really happy with the boost on speed the game got.
I know Arena has enough slots for fighters, but i already use all, i want more :P Is there any particualr reason for the limit?
