a solution would be to keep track of the time between clicks and enable clicking if its around dt time which is basically every 0.15 miliseconds, any click faster than .1 milliseconds shouldn't count, as cookie cliker games are very intesive when u will have a lot of autoclicks happening + the clicks u do.
so variable lets call it trackclicktime
everytick add to trackclicktime 0.01
on tap if trackclicktime greater or equal dt set clicked to true. or add 1 to clicks.
on tap set trackclicktime to 0
that way you avoid cheats also.
this solution won't make the clickcounter be working faster, but will be accurate(and close to frame dependency... for more accurate 60/fps calculation u compare the trackclicktime to (60*dt) ) and work everytime as each click must be at 0.1 -0.15 apart from each other.
