Stupid use of Kobans just to finish collecting all $ from harem or complete daily missions. Is like they think we are impatient. Also, misclicks are a fucking Bitch.

Too bad, it's rare to earn Koban compared to other Nutaku game currency where they give you daily logins or mission completion rewards.

Why charge any resources at all? Clicking the buttons individually doesn't cost anything at all - it doesn't take kobans, energy, or even any meaningful amount of time; why should a "Collect All" button charge you for clicking all the buttons for you?
