This game is pretty cool.
I like the style and the movement animation for the plane as it crosses from point to to point.
some sound effects would be nice, and maybe a menu or a pause button?
Also have you thought on trying to make the movement more in the players control? from what you have now, you can tell that the plane moves to certain points on the screen, which works fine but giving the player full movement would also an interesting way to play, especially with the pitch and roll of the paper plane.
