There are only some small imperfections.
For example there are discrepancies between the proposed naming of your GameObjects and the names viewable on the illustrations.
(Img_Header vs. Header etc.)
Good spot @hansmuster As you may have noticed, this was an update to an existing tutorial. As part of the update I changed the naming convention of GameObjects and must have missed this one in the text of the tutorial.
I hope you found the the tutorial useful and also checked out Parts 2and 3 :]
