Wing and a prayer
Tiny Wings may revolve around the same kind of animal as Angry Birds, but that's where the similarities end -- Tiny Wings is an entirely different game to Rovio's smash-hit title. Developed by Andreas Illiger, Tiny Wings' protagonist is a small blue bird who's always dreamed of flying but has, er, tiny wings.
This tiny bird's world is full of hills that you can use as impromptu ramps, propelling the critter into the air. The aim is to keep the bird flying for as long and as far as possible before the sun goes down.
When night comes, it's game over and you have to start again, but you can avoid this by moving across the landscape as quickly as possible. Every time you complete an island -- a stretch of hills -- you'll be propelled into the sky, and land among a new set of hills. Completing an island will push the sun further back into the sky, giving the very cool impression that you're racing across time zones.
Let the birdies hit the floor
Like all the best games, Tiny Wings tests your timing. When you hold your finger on the touchscreen of your chosen portable Apple device, the bird stops flapping its tiny wings and drops like a stone. The secret is to drop onto the downward slope of each hill to gather momentum, and lift your finger off the screen when you're on the upward slope, propelling your bird into the stratosphere. You then repeat this, with every accurate drop firing you further and faster.
That's about all there is to Tiny Wings. It will take you a while to learn the physics of the game, so, if you're after a quick fix, you'll find games like Angry Birds require less mental investment. But, whereas games like Angry Birds and Doodle Jump can at times feel random, unfair and frustrating, Tiny Wings never does. Also, once you've got to grips with the momentum-gathering technique, flying through the hilly landscape feels really exhilarating.
