I finally released the demo tonight.  Several bugs were immediately reported, so I will have to fix them before expanding on the PvP fighting engine.  Some of the bugs are:

1. Spectators seem to "replace" fighters in battle

2. Character selected doesn't always stick for battles

3. Spectators cannot watch the action in real-time

4. Battles sometimes don't load correctly.

5. Two of the same character won't show up right on the DSi.

Things to add are:

1. Damage calculations

2. Tie in to Mt. Hildar

3. Multiple characters per player

4. More content

Still, aside from all this, members seemed to have a fun time trying the demo, which pays much of its homage to the old Final Fantasy games.
