Love the story line... why don't you do a chapter sharing job with another writer. get a basic plot synopsis and find another character to share the "protagonist status" more effective if its a girl.
Finish one chapter, send that chapter to the second writer, get her/him to write another chapter about what happens after that but from their perspective. that way you have a mixed viewpoint, then get them to send it back, then repeat.
The enemy is called 'the glitch'
She was created by a hacker to destroy all games as it was 'destroying humanity'
