Me and a buddy just tested this out. We play a match with 7 rounds. 1 life a round.
He killed me 4 times winning 4 rounds with 4 points. This was in the first 4 rounds.
I killed him in the last 3 rounds. So I won the last round.
At the end of the match I won with less point AND less rounds won just because I won the last round.
This needs to be fixed.
I tried to take a screen shot as proof but the game conveniently left the scoreboard out of the screen shot
