I have a few problems with the game and some suggestions to fix them with the first being that, the camera sensitivity is a bit too high. To fix this I think you could add a settings menu with the option to reduce camera sensitivity.
Next is the issue of the game's Christmas theme. I don't mean this in a negative way but, if I were to let a random person play this game without them knowing that it is a submission to a Christmas themed game jam or reading the game's name, I doubt the person would have an easy time finding out that this is a Christmas game. To fix this you could, add some of the holidays most iconic decorations such as trees with ornaments and tinsel on them, stockings and candy canes on walls, snow men littered around the map, the list goes on.
lastly is the issue of the door to your little present making cottage. After I finished collecting sticks and tried going back to the cottage to build presents with them, I found it a bit hard to find the door due to it not standing out that much. There are a lot of ways to fix this and some solutions that I can think of from the top of my head are, making the door bigger and changing its color to something more noticeable.
One thing I really liked though was how you did the shadows of the trees and made them move and sort of wave around with their tree.
This was a pretty decent game for a week long game jam and I give it a 3/5 for effort. I really feel that if you had some more time you could have done a lot more with this game and expanded on the core mechanic of creating presents by making more materials to create more presents with, giving each present its own unique model and implementing some kind of a crafting system to make building presents more interactive.
