In Good Company by Michael Dooner - Comedy, Play - This Play concerns a comedy of errors, from start to finish, at a dinner party. The novel feature about this play is that people’s real emotions/feelings are demonstrated in the script by being underlined, with their respective name beside it. This can be achieved in the theatre by an over-head light, speakers, or a freeze-frame/pause in the action; whichever you feel suitable. 86 pages - doc, format

First things first -

Plays have a manuscript format. You need to check out some websites, or buy a book. My go-to website is http://www.playwriting101.com, and my favorite book is A Playwright's Guidebook by Stuart Spencer. http://tinyurl.com/2hvrq7

Another thing: How do you pronounce "Aoife"? Either use names people can understand, or include a pronunciation guide.

Your "novel feature" is called an aside. It's been done for ages. Shakespeare used it in just about every play I've read. It's the same as dialogue, just with (aside). I think there's too many of them, to be honest. Like anything, the more you give the audience, the less "novel" it is.
