I took a quick look at the game and have a few things that could be improved. As a small change, when you restart a level leave the elf at the same position and angle so that a player can hone in their shot. Also when I broke all the ornaments, and knocked over the tree getting a score of -8000 the game still said good job. You may want to change the logic to change the end message depending on how well or bad the player did. With extra time you may also want to try improving the animations; the elf walks very stiff, and while making animations quick is necessary in a game jam sometimes, you have extra time to add polish. Finally, there are a lot of dissonant chords in the music. It sounded a little like a young kid just learning piano trying to play a Christmas carol, which may have been what you were going for, but with all the chords evenly spaced the dissonance becomes too much.
