Not a copy, what i made is MUCH simplier. Did you notice that my program is very small window? thats because it wont disturb you while doing other internet work. Seriously i would like to make it catching packets from game itself so timer would be accurate, but i have no such skills.
Autoclicker is no problem, oh wait it is problem. Autoclickers (or "macros") are not allowed, because it gives your unfair advantage. Did you ever heard of russian "aimbots"? autoclicker is that case.
And if you want i am able to improve it that it wont be copy by your opinion. For example i could make it switch focus on game window when timer finish.
