Impossible challenges

[Sephira]

I don't know if others also have problems with this but with many of the harder girls or in other words those that scale by 300+ i find it pretty much impossible to do the challenges of the last 2 stages the amount of clicks you have to do while aiming for the right spot is insane. I tried challenge 8 of Kimberly more then 20 times only to come up short at the end. I would love it if the scaling difficulty of challenges was a bit easier or if we could buy something to increase the timer of the challenge

try changing the size of the girl to min making it less movement for mouse many areas share a sweet spot such as breast and arm.
