I'd like to say, the game must have an eighteen more version on the phone. You can market through Nutako.net or Erogames.com
I'm fan of this game.
Actually, it has. You can download it at taptap global which has a R18 version.
They only need a way to give uncensored to iOS users.
Nutaku doesn't have a good record of catering to its players.
You can also download an uncensored version. It's as simple as dropping it into a file in the file manager. But it's a mod.
For Android, which has a file manager, of course :p
