Decent game. It was good, not great, but that's not because of the game, it's because of the concept is overused.
It's much like tetris, except it has much more free physics.
Some things that bugged: Leniency on controls. I REALLY hated that the MOMENT the gifts touched anything, you lost all control. I had no chance to "fitting" the gifts together (Like the bear+gingerbread man), and it frustrated me so badly <.<
Some of the gifts can "connect", but i cannot manage to actually connect them 8/10 times... which means it's luck when i do, and that's not especially pleasing; In generally it feels more rewarding when you KNOW it's skill, because you can pull it for 9/10 times :)
The replayability is LOW for this kind of game; You should consider some "modes", like, Gingerbread+Penguin only, or "all gifts are now bigger" or "you only got half the time, but the gifts fall twice as fast" or something derp like that :D
Also the screen lagged when it scrolled upwards when you got above ~350 height in your stack.
Decent game, a safe choice, not much could go wrong in making this. Not so "adventurous" a choice of game, but it was pulled off well, albeit it lacks replayability for a game of this kind.
