its a great game actually, and presents a small challenge in the high levels. And is totally Christmas themed.
And has a world high Scores list (which I managed to land a few of)
But yeah, it uses the keyboard... but I use ControlMK and use my controller

And not every note is worth the same amount of points
(kind of like DDR with the "Cool" "Perfect" and "Poor")
It has "Jolly" "Merry" and "Humbug"

But yeah heres some in-game
(the presents have hit-flames and disappear when you hit them
