I just completed J-Dungeon for Phantom Menace's demoquest v.2.10
I can't seem to figure out what to do next.
I have the: Boomerang, Bombs, Candle, Arrow, Raft, Ladder, Some bag? (what is this for?), magic shield, braclet, white sword, and the blue ring.
Seriously though, what does the bag do?
The bag allows you to carry 500 rupies instead of 255. You'll need it to buy the Magic Book, which costs 350 I think.
I haven't played the Demo Quest in a while, so I'm hoping this info is accurate...
From the northern exit of the J Dungeon, head west to the graveyard to find a cave with the Magic Wand. Gather enough rupies to buy the Magic Book, then go east to find a tree that can be burnt with the Magic Wand and Book. That will create a bridge to take you towards Level 1.
EDIT: Nevermind, I found everything. I've also found both entrances to Level 1 (West and North)
