Black Swan (Hidden Object Game)

Hi,

There is an error when i play, i can't enter to Mirror World.
I can't complete the "Release the girl locked under the dome."
When I enter to the girl, I have black screen with only inventory bar visible.
When I try to use the Wooden Hand with black screen nothing happens.
I can't complete this game.

Also, when i click on the white swan to get help it's write :
"Perhaps i will find something interesting somewhere else.

According to me, it's a Beta game, a game not 100% developed.
