Real quick I'll detailed how I found this game which I have fallen head over heels in love with
I loved Avatar ever since I first saw it as a kid, however I also have always been a massive pervert, my sexual development can be traced primarily back to Meet n' Fuck on Newgrounds, so I know what a porn game looks like, basically on instinct. So there I was at work, browsing memes on iFunny (which is terrible I know don't judge me) and then I look in the comments and find a still frame of Azula from Book 2 and instantly I know "Oh. This is a porn game. About Avatar. One which I am not familiar with." and so I scrolled down, found the name "4 Elements Trainer" wrote it down on a piece of rag from work and went home, looked it up...
and here we are.
I'm sure something along these lines has happened to thousands of people since Netflix put Avatar up on their listing.
