I got as far as 43, was that good? Sometimes I would click and see the button react but the game wouldn't but that might have helped more than it hindered towards the end!
That i Score is butter then my record the best i got was 37 but the game gets harder up to 35. The button not reacting is do to how I code it so you could not spam it and git a lot of points in the zone but the time seems to be too long latter in the game. Thank you for your feedback :).
