It is solved! For all who can't see others workshop items.

Hi everyone!
This is a shocking thing that only i can see the workshop items and download them in game.
There are two users say they can't play other peoples puzzles in game. But i think it maybe the net probelm.
Today i found the real reason:
It is the Workshop Visibility State. It is only can see by developer in default....
Now i change it to everyone. It is fixed.
Now there are 146 items exist in Steam Workshop. They are amazing beautiful!

Wish all people to see other's masterpiece.
Thank you all!
