Hello! there's an exploit, i don't know if it has already been mentionned but due to the fact that kill count doesn't update until another thing is updated (for example autofight toggle button or skill reset etc), you can keep fighting enemies whose pictures aren't coloured red by clicking them even though you've already reached the maximum fights you could normally have. For example, before my first prestige, i had fought and defeated more than 20 times the eye, thus recieving 20 times it's reward, same for golem or hydra or anything else. I hope this is helpful for the dev.
