You weren't kidding when you said this game was challenging. Half the time, I'm not even sure exactly what I'm supposed to be touching. There are shades that match certain parts, but then they don't let me beat the level. I guess I have to give you credit for having something creative. It's too bad it isn't Christmas related. The graphics are nice and simple.
I also think the music is quite suiting. It's quite strange, but probably worth a shot for fans of puzzle games. I myself am not really one of those people. At least you can get the hang of it after awhile. I can't really suggest improvements, because it works so well with what it's supposed to be.
