I expect this score will be blown out of the water pretty quickly as I got a time out at round 6 which cost me any points I had earned previous to that! Haven't figured out the best way to score high yet, certain moves will give you lots of points and you can spam them til the counter starts getting low, but you also get a pretty damn good bonus for any time left so it may be worth going for the quick finish :).

The score disappears after the last round so get ready, but wait to get your time bonus added on! Quite tricky to catch it actually!
