Like the title suggests where are the secret buttons for the castle tile set? I'm trying to think back if I remember pushing any while in the castle in the main story. If there's not are there any work arounds?

There aren't any. Workaround: use a regular button.

Or wait for someone to create custom secret buttons. If you wait they will come.

Already working on, after if ound a solution for these F#'0@ing animations of trapdoors xD ( The same animation system to implement, but seems that animations in one object is coded differement according to the object )
