Android Game like Flappy Bird

Green Bird is a side-scrolling mobile game featuring 2D retro style graphics. The objective is to direct a flying green bird, which moves continuously to the right, between each oncoming set of obstacles without colliding with them, which otherwise ends the game. The bird briefly flaps upward each time the player taps the obstacle on the screen. If the obstacle is not tapped, the bird collides with the obstacle and falls due to gravity. The player is scored on the number of obstacles sets the bird successfully passes through or avoids, with medals awarded for the score. Like Candy Crush Saga, Green Bird is in nest-stages identified by city names. Once a player selects a location, city names are used for the names of the nests. Using Toronto Canada as an example, there will be nests like North York, Forrest Hill, Etobicoke, Thornhill, Scarborough, Beeches, etc I have added sample bird obstacles - buildings in Toronto When a city is completed, the bird moves to another city...then to another state or province, onward to another country in a continent, where the bird starts from a city, then ALL states, then another country....then another continent, until the ENTIRE planet is completed (or never) then the bird could go to the moon? :). I hope you get the gist.
