This sounds like it would be really fun. I need to work on my voice acting a bit, since I'm in improv theatre anyhow, and be able to fluidly alterate between characters. I was thinking along the lines of a first person story, where the storyteller is a schizophrenic (I just did a right nasty final about Poe and his supposed affliction). And not just crazy, over the top. I mean contemplative, degenerative, self-indulgent madness, so sure that he is sane but his completely out of it. Plus the people he encounters after he breaks out of his insane asylum.
Ooooo, I can taste the delicious Store Credits already.
