Yeah... nice multi-ball! I'm playing the 5 minute challenge for the same tournament now (on XBox One) and hopefully seeing your gameplay will help me get a better score (and beat you ;-) ). I'm not a big fan of the 5 minute challenge. I rather prefer 1-ball.
This was on PS4 in a community league (OPPL). I think 1 ball is my favourite mode (without upgrades) - it seems like a pure test of skill. 5 minute modes can be fun to find the quickest way to score points.
