Problem with lifting the cage to free the bird

[tonicres]

I think it's game failure, but try to lift the cage but it does not work. Does anyone know the solution? Thaks

You have to open the "door" on the cage. :)
Do not lift the cage :(

I tried it and it did not work, and I think that in a video game guide I saw how the brother leaned on the pulley that opens the cage, but I try it the same way and I can not get the older brother to take the feet of the younger brother. Can it be a bug of some version of the game?
