@poubel thanks for the suggestion, i will try that in my next game :) , i know the pattern is easy to be figured, pattern level 1 and 2 is same, thanks again for your suggestion :)
@zdar thanks for your suggestion too! but i am having difficulty at slowing it down, first i am slowing it down instead of stopping it, but some balls stuck at the edge of screen :(
this is my first game, thanks for all your suggestion :)
