You gain an energy point every 7 and half minutes. Otherwise you can pay 40 kobans to refill your energy meter.

So when it comes to pricing neither myself or Greetingz controls that.
I would love for things to be more "reasonable" as a consumer.
This is a product of not only this genre of games (hentai) but also of F2P games in general
Let's say they charge $5 per girl (random) instead of seemingly $40 USD.
So 8x more people would have to pay instead of the one taking the plunge.
Theoretically it should balance out, it being more affordable means more people would buy it right?
Unfortunately, I just don't think that is how it would actually work.
People play F2P games so they don't spend money.
