The free-to-play games.
This game is set in Australia. The penguin stands on one side of a see-saw while the yeti stomps on the other end. If the stomp is executed with good timing, the penguin lands on an albatross flying overhead. The player then has control over when the albatross flaps its wings. The closer to the ground the bird flaps, the more efficient it is. When the albatross' energy bar (which slowly recharges when the bird is not flapping) reaches 0, the bird will soon crash. It was originally released in 20
