You should have used my flappy-accurate "Wafty Man" code: https://github.com/mrspeaker/wafty-man/ - it has exactly the same rotation and physics as the original ;)
Oh, I didn't know Wafty Man was based on the typing tutor code. Wafty's been the most accurate flappy bird clone I could find on the app store by far. It's impressive, same guy behind the two ;)
