Birdie Up

It is finally springtime! The first flowers and grasses awaken from hibernation and a cute little birdie too. After the long winter it is hard to make the first flight attempt. Push a button to flap! Birdie Up is a simple but addictive game. With a pushing a button on your controller, the tiny bird makes a flap with its wings. As faster you tap, the faster the bird flies above and you get bonus score. Try to get as high you can to beat your own high score and don´t be so angry if you lose ;)
