Hello I kind of stuck in Mechanical age , any help please !

Need more info.
How far did you get.
Where you in the age.
Where are you stuck.
The more info will help someone give you hints.

I'm inside the age , but I don't know what todo, I already saw the secrets rooms , I have the blue and the red letter, but I can't move the building sorry If I don't specific too much , my english is not good

In one of the rooms you should see a miniature of the building that you can play with. Move the building by using levers and listen carefully to sound that is made when the building stops at the next point. It is a matter of timing and sound. Play with it to get familiar with it. If you need more let us know.

thank you
