Very nice and well made game! I really like the fact that you don't have to send 150 gifts in one run, otherwise, the game would've been impossible for me :P
I enjoyed the game, but I think that you should make so you don't always have to enter your nickname for the highscores again and that the game just memorizes who you are. It would be nice if you add different gifts that have different sprites and give your more points, but are a bit harder to get.
Anyways, good job on this game! ;)
