You control a green bird which jumps up when you tap it. It is influenced by gravity, and will thus fall until you tap your screen. There are 3 collectable items; whiite, yellow, and green. The white one pertains to score, and collecting the white collectable increases your score by 1. The yellow collectable corresponds to coins, where collecting one gives you one coin at the beginning. You can later unlock the green collectable, which is a shield. Throughout the game, certain obstacles appear. There are 2 of them; blocks and vacuum.
