The Katelabs Advent Calendar! 25 doors each containing a small world makes this (I believe!?) the biggest Katelabs world to date!

FAQS:

Q: can I open all the doors at once? A: yes, but if you do you have to leave a comment as a trade.

the idea is that you select the day that you are on and it give you a fortune, that's it
