Is it strange to everyone that there are so many mobile games that have been popular that have birds or penguins as the main character? Angry Birds, Flappy Bird...
Ya, but at least Angry birds was cool for awhile. Flappy bird is a bunch of monotonous horse !$&? IMO( I don't understand the popularity of it at all?) it bores me after 10 seconds...
I just got and am really liking flappy head. It is great to play, tap and your head moves up and down. Don't crash or it really hurts. One of the best jetpack joyride clones ever. Play flappy head, and you will be extremely satisfied.
There was also Tiny Wings. Not hugely popular anymore, but it was at the top of the charts for a long time.
