Yeah, I would have to agree with Chris on this on.
A suggestion, though:
Create two systems per episode. You also probably should go back to episode 1 and 2 to include the lose path systems while you wait for voiceovers.
Another piece of advice, judging from your news posts, you might want to have a few people beta test your game before releasing it. Even though the file size is small, making people continually redownload the game is not a good thing.
Also, if you are not already using Wedge's WC site, I'd highly recommend it as it is extremely comprehensive, IMHO.
Just some helpful advice.
