Interesting...and yeah, Chickenlump is right. DON'T publicize! I've been beating ZeaLitY with a stick lately about publicizing Crimson Echoes too much. -_-
Personally, I think the story sounds a bit too...I dunno...repeated? The people-being-tortured thing was confusing but it sounded just a little too cliche that ALL OF A SUDDEN the future is probably gonna be crap again, Zeal never really died and the whole freaking city is back, along with another "version" of Lavos that's basically supposed to be a zillion times stronger.
If you have too many of the familiar images we're used to seeing, people will think you're making a movie of Chrono Trigger, and not a movie-sequel. To avoid this, you'll want to use some new concepts, such as...maybe Zeal is successful in summoning this new demon without getting her whole kingdom mutilated, and thus the kingdom of Zeal may still be flying in 1000 AD? Seeing Zeal in 1000 and all the townspeople acting like it's just there and just completely normal...that would be quite a new concept.
Anyway, but hey, your production. Just my 2 cents.
Best of luck to you.
