Thanks for playing!
I'm sorry it was too difficult for you :(
My tips are: focus on slower conveyor belts at first, be efficient with the lines, and try not to let too many balls fall to the ground or you'll waste too much cash.
Otherwise perhaps you'd like to try Version 1 which is considerably easier (available as a download).
After the rating period is over I'll consider adding difficulty options to make the game more accessible.
