Hi, I just released my first game Evil Fly, similar with flappy. I know it is not good but it was really didactic for me. I learned using BB platform, adding advertisement and releasing in AppStore. I hope I will do it better. Here is the Evil Fly https://itunes.apple.com/tr/app/evil-fly/id1441136536?mt=8
I am a big fan of flappy and if your game is similar then I would like to try it to see what it looks like
