Hey! Thanks for the kind words! There are two additional endings revolving around your rank. If you correctly pick the option every day that lets you win the match (hint: stay on the payload), you'll get the grandmaster ending which has an additional cut scene and gift at the end. The same with the bronze ending, only you'll need to win no matches instead of all of them. So, it won't drastically change the ending, but there will be some additional illustrations and achievements.
