To be honest @onceuponatime I am pleased on both fronts.
#1 I am pleased that you received so many entries
#2 I am pleased that you have a conundrum
...because that was exactly what the mystery door was... a conundrum.
Conundrum: a confusing and difficult problem or question.
More than prizes, awards, and judging...
I found this entire contest quite fun and spectacular for finding a way to energize everyone.
If anyone deserves a prize for this.. it is you.
P.S. Re-steemed. This was the most out-of-ordinary contest I've seen in a long time. I loved the suspense, uniqueness of it... and how everyone got involved. What a way to build community involvement... even in something as obscure as this.
A lot of fun. I hope you do something similar, but different again. :)
