Bad Plot Monsters and Evil Grammar Demons

In the comments to the “Whaddya Want” thread, Patrick M. posted an interesting request:

I’d like to see a side scrolling video game where you save manuscripts from the slush, battling bad plot monsters and evil grammar demons while dodging bipedal cows that don’t hold your interest.  And collect paper clips for a power up.

You know, now I want to see that too.  Anyone out there got the chops to make such a thing?  I’m sure the writing community would love you for it.  Or I would anyway.
