There's a new iPhone game that is taking the app store by storm, and it's called Tiny Wings. You are a little bird that has, you got it, tiny wings. It has trouble flying so it relies on the hills where it lives to get up enough speed to jump to the next island.
The controls are simple, you touch the screen to tuck your wings in making you dive downward. That combined with a downward slope of a hill gains you speed and more height coming off the next. You gain points for collecting coins and speed boosts. You start out in the same place each time striving to reach farther each time you play, discovering new islands, before night fall. When night sets in the game is over and the bird falls asleep. You receive multiplayers for completing tasks that allow you more daylight which allows you to go farther.
One of the cool things about this game is that it changes every day you play. It has Procedural generated graphics which changes the levels look and hill layout every day you play. The game sells for just $.99 and it's a must have. It's super addictive and a great time waster.
