It was the top-grossing game in the App Store for two weeks from late February to early March 2011.

The game play mainly revolves around timing the player's taps so that the bird slides down hills and flies up them.

The game features special missions to upgrade the player's nest and increase their score multiplier.

These challenges revolve around reaching specific islands or achieving certain feats a number of times in one game.

Designer Andreas Illiger made the game with the "dream of flying" and positive emotions in mind.
