I tried to download it, but it was gone in the AppStore by the time I heard about it. The Vietnamese creator of the game was pulling in 50k a day in ad revenues and pulled the game out because he was getting harassed (say woot).
Since then, flappy bird clones have taken its place. I downloaded Flappy Wings which I heard was even tougher than the original. I liked it a lot -- you get to shop for different hats, Indian headgear, crown, Santa hat...and the bird poops tomahawks or candy canes depending on what hat you got on. My current score of 384 placed me at rank# 110 on GameCenter, but I saw a lot of hacked scores (most of then at 5,000), so my real rank could be in the 30s (out of over 5,000,000 players).
Here is a screenshot of my high score. :blink:
Tips: Tap while the bird is coming down at about a third of an inch from the bottom obstacle. When climbing steeply, try to do double or triple taps in quick succession. The 2nd image shows you how to properly recover from falling. Oh yeah, keep your focus at all times and practice.
