Most of my writings are here... I don't use any software other than the engine, or notepad... and not many differences between those two, although in ES there are a few.
I've had a quick read of a few of your texts. I can see you're stretching out your literary muscles. There's no shortage of content.
If I were to suggest anything, it would simply be to clarify the character you are writing for with a brief explanation why they're the way they are; and then to put your character's words in a contextual grid. What kind of grid? Imagine if you will a spreadsheet filled with the character's sayings where each row is one of a multitude of moods and the columns are possible states in the storyline.
The freedom that comes from having a character who can respond to circumstances and their own personal issues feels very much like a living breathing entity. I'm sure you may have had some situations in mind when you wrote your work. Making the character's intentions explicitly easy to read not only assists a developer copy+pasting the text for the appropriate places, but also for you the writer who can muse on how slight differences in circumstance would reflect a different delivery by the character.
