Make a Xmas themed game during the Xmas!

Rules:

• Xmas!
• every approach to Xmas (consumerist, religious, blasphemous...) is fine, as long as it's in good tone and not offensive
• source code and assets need to be released on CC-BY-NC-SA 4.0 or compatible license
• you can work either alone or in teams
• you can use ready-made assets, but only if they're freely available for everyone else
  • however, it is encouraged to do as much as you can by yourself
