After seeing the Flappy Bird game do so well thought I would have a go at making a similar game, then the clone jam started so thought it was perfect time to actually make and release a game.

Works just like the original game but has four different levels, each with new graphics and slightly different flight settings.
There is also a shop to buy new characters which decrease in size and also hearts so being hit is a little forgiving.
