Alright, so the quick demo is almost finished. I should have it done by tomorrow once I get back from the DMV and Voter Registration. Right now eveything is a default sprite, I don't have any custom sprites to put in yet. The towns and other locations aren't too detailed (then again, I could never make a good map or town xd ).
But yeah, the demo ends with Stream wiping out the party. You start off with Pi, find out about the bards, exit town, and follow the path to the Monk Monstary where you meet Zely (I have the game set up so that it directly warps you to Zely, any and all story/leveling/etc is held off for the time being). You exit the Monstary and follow the path where you'll meet Skizz. Like Zely, the story of how you meet Skizz, whatever leveling you may want to do, etc is all held off (I have it set so you gain levels and items when you enter the location).
From there, you exit with Skizz, follow the path, and meet Mala. Same process will follow. From there, you leave the place, follow the path, and enter a location that will put you in the scene right before you fight Gator Prime. From there, I'll have it set so you lose (basically, Stream'll be unbeatable, 999,999 HP; 9,999 MP; 999 Str; 999 Int; 999 Def; 999 of everything else except Agi, that way you can get a couple of hits in). He'll do a special attack (probably Devour) and you'll find yourself in his gullet. That's where the game will end.
Remember it's a really rough demo so you may run into glitches and stuff, but I think it'll be fun for the most part, just to give ya a feel of how it'll work.
