Who said the mobile version didn't have the R-18? It's the *Google Play* version that doesn't have R-18, nothing here on this page has been removed, unless somehow I fucked up, LOL. You should be able to download the mobile version here and play the R-18 stuff, assuming you're over 18, of course! ✌
Sorry about that! Looks like it's just a mistake on my part and nobody had brought it up until now!
Some stuff probably just got mixed up when I was putting up some translations, it happens sometimes! I make no money off this game, and folks don't usually support my other work even if they like this game, so it's hard to keep updated with it. :S Thanks for your patience!
The game is gonna get an update within the next few months to fix some compatibility issues, so it'll be fixed then. Follow my page and you'll get the alert when it goes up.
