Although this comment will be in the same veins as all of those that you got already, I'll take the time to write it, just to make sure that this idea doesn't get left on the side of the road : great idea, probably lots of fun to have, allows people to be creative together which is awesome, and probably lots of room for great ideas on your part to improve the concept, but i couldn't play it since, you've guessed it, no one's there at the moment and I don't have another half hour to waste by just staring at this screen. Hope you'll follow through with this !
Edit: Alright, just finished playing with you and a bunch of other mad lads, and it was pretty cool ! Lots of fun writing about sharpened rubber chicken and whiny Timmies, and bad coders.
I think that what's the most important to fix is the timeframe during which you can write, as well as the time you give us to read the story. Maybe a way to save the story somewhere would be nice ? Like some sort of link maybe ? The other thing enjoyable would be a sound notification when players come in and out, and when a game is about to start maybe. Or at least settings for us chose from, y'know ? Cause right now i'm writing this comment and I have no idea if people are playing or not in the meantime. This game has lots of potential, very simple principle, but utterly fun. Hope to see it bloom !
