Uhm semajaguar it is more points earned for winning quickly. I challenge you to earn more points by playing longer.
You get extra points for how much you curve the ball but your time bonus goes down every second. And if you play too long you get points deducted.
So good luck getting more points by playing longer.
And upgrades are awarded by hitting the lines. Read the tutorial.
Actually Gator I made the comment because I released the game about a year ago and got the CURVEBALL CLONE blasted at me. Yes it's very Curveball like, I completely agree. But it's as much like curveball as gemcraft is desktop td. It's two games in the same genre.
Well maybe a little more like curveball than gemcraft is desktop td but I think my point is clear.
Thanks for the comments though gatorbeetle, greatly appreciated. And Curveball is a good game, definitely. I played it many times.
