Your game have nice graphics but... it's a bit weird to play.
First, can you include a "How to play" screen ? Or telling us how to play in the game description ?
It was a chance i clicked then it made moving my Santa.
Now the big problem of your game is :
When you change to an other layer, Santa don't go right down under himself, he moves a bit to the right, then when he came back to the top, he came back to its first position on the left.
It make the game really not fun to play because you can't aim clearly.
I won't complain after the fact that we can only go down, it can be an original concept. But it can't work great because of the point above.
