Once you have the tree in your house you can look at it from the desk point of view and climb up to see the rest of the tree. However, you can climb even further up, beyond where the roof meets itself. If you go further up from there you will find yourself in a vast black static screen. Don't know if this was the bedoeling, just putting it out there.
It was a bit too easy, and you get medals for just playing the game. This I find strange, they are easy achievements. They should be achieved out of greatness, or because you did something out of the ordinairy, for which you are then rewarded.
Consider raising the first song, only a small group of audiophiles will be able to hear those frequencies clearly.
Overall I found the music entertaining, and the art was pretty good.
