this should be wishlist stuff. Why not just ask what you want? you want a deathmatch mode so you can just kill people instead of helping your team destroy the enemies ball.
Probably should be in the wish list section I agree... it would be a great game mode to have longer matches. I feel that as soon as I have all of my skills upgraded the game goes into overtime! Maybe the bot levels should increase after a period of time too... like in blitz!
Through a lot of play testing we found 15 minutes to be the best game length. When it got over 20 minutes it would really start to feel like a slog. We actually had it at 10 minutes for a while but we felt it needed to be a tad longer.
I wouldn't like longer matches. 15 minutes is just about right, if you still want to play you just play another. I find "longer games" and "bigger games" are two things people always ask for without considering the consequences.
I just hope if you implement private matches you would allow people to set the game and overtime time for themself. I think much fun could be had with that.
