This is a very simple but fun game.  Your object is to jump as high as you can jump.  You must bound from object to object in order to reach as high as you can.  As far as I can tell, there is no end, you just keep going until you die. 

The challenge of this game comes in moving from stationary islands to the back of moving birds.  As you reach higher levels the birds change and fly faster which of course means that it is more difficult to aim your jump exactly where you want it to go. 

My only drawback is that the birds make sounds when you jump on them so it gets annoying after a while.  However, there is no music so you can always just turn down or off the volume to avoid the sound of birds being jumped on.

Overall this game is fun to play if not lacking a bit for variety.  It’s worth checking out though.
