Really really nice game. Graphics, sound, levels, upgrades, but.... It is too easy, far too east to get upgrades by replaying the easy levels where you get easy gifts. The only difficult thing is to get three stars for all levels. Make it more difficult and this is a 6/5 game!
looks nice, sounds nice, decent gameplay at the start, but too much of the same after 5 minutes. Try to make more interesting gameplay and it will be great!
