You got bugs...
First you should know that the jewels that fall furthest to the left of the screen and a set of money bags that fall in the centre screen cannot be collected for some reason. They just kinda keep falling.. so you may want to look into that.
It's not bad I suppose... I think it's an interesting start, and I think if you keep working you'll learn to expand your flash capabilities. But you may want to make the game more interesting. Add some more stuff to do so that the game isn't instantly boring. Add some obstacles, maybe a bit more animation, a storyline to explain how collecting falling jewels has anything to do with learning to fly perhaps... but most of all, have different music! That was really irritating and repetitive.
you can also give options like turning the music on or off. Your graphics seemed relatively okay, but it could also be interesting if you programmed the eagle to swoop and stuff when he turns corners instead of the total linear up, down, left, right sort of thing...
I hope that helps. All in all, not a bad effort. Keep trying.
