Good job! I really like the premise, and the music is very good. However, the character movement seemed a bit clunky. The elf continued walking for some time after I stopped pressing the buttons. Additionally, I couldn't make sense of the barrel things; are the parts you take out of them (the head and the body) random? But overall, it's a really neat and nice game! :D

This is a good game for your first game made, especially in a game jam. If you want to improve on this game, here are some suggestions: 

-Make the player move faster. 

-Make it so that the player can craft different kinds of items instead of just rubber ducks and robots. 

-Increase the timer from days 7 and on. It's impossible to craft all of the items on time unless the player uses an exploit. I found out that the best way to beat the game is to continue moving while Santa's note is on the screen and while the timer disabled. This way, I could craft all of the items on time. 

-To remove the exploit I've mentioned above, make it so that the player cannot move until they close Santa's note.
