This looks like a great template! I'm just getting into Sugarcube, not to mention css, javascript and everything else I need to know to get an IF up and running the way I want it, lol. Checking out your template is helping me learn a lot, thanks!

A couple minor things I've noticed while playing around.
1) On the Is This You page, it returns Your full name is Jane $astname. I'm pretty sure you just forgot the 'l' in the cust-review Passage. It also says You have $eyecolour eyes. Looks like you just need to add MC_ before all three eyecolour in the cust-review Passage.
2) In the Saves and Settings dialogs, the semi-transparent box seems to bleed over the bottom border if the page is zoomed in too far.
