Very cute. The start is a bit slow, I had to wait 15-20 seconds before I revived my first gift to regift. But the game is very cute and charming. And the game over screen is great. Good work. 

This game has really simple rules. So easy that it's not required to read tutorial section. Which is good- it fits the theme. I like the idea about giving and receiving gifts from others to others. However I think player should be able to look in box from the buttons panel instead of clicking on gift showing above gifters' heads. That feels a bit strange to me.
Game itself is fun to play, sound effects are good, music is catchy and graphics are fine. Mix of flat, pixelated sprites and blurred, 3d boxes floating in the background gives an unique feeling.

I liked it! The simple mechanics make it easy to play!
