Happy Bird. app for iPhone and iPad
This is a fun pixel game, regardless of its simple form but extremely difficult. It has a simple but not rough pixel picture, a cute-looking bird, and a few white clouds.
Gameplay
You need to constantly control the frequency of clicking on the screen to adjust the flying height and landing speed of the bird, so that the bird can smoothly pass through the pipe gap on the right side of the screen. If the bird accidentally wipes and touches the tube, the game is over.
