I've reached lvl3 entered the Cawic City affected by some plaque, got a cut scene with Mr Blue he offers the three gifts if they can find the source, it is in the purple dungeon to the North West corner. I couldn't beat the boulder monster, or whatever the fuck that thing is. Make sure the MC's perception is high enough go into the Cawic Adventure Guild you should see a colored circle in the center of the building, if your perception is high enough you should get a dialog box saying somethings hidden under the countertop, go behind the counter and search to your left there's a hidden lever it opens a trapped door go down and defeat (what I think is) a female orc, after defeating her leave and you should meet the female demon responsible for the 'plaque', Mr. Blue (Dusas) appears and stops her from attacking the MC's team. The plaque is gone, it's just an abandoned city now. (SIDE NOTE: Go into the INN/PUB you'll see an envelope sitting on the floor choose 'read it' its the 'Pen Pal'. Return the letter to the female and both quests are done.
However I did find out something else while in Nulbadin go into the Inn and talk to the few people in there one is a bounty Hunter named Mr Grimm. He asks you to keep an eye out for a wanted thief. I also found a "Beach" that allows you to advance the time into the night (also a few CG pics). While its nighttime go back into the Nulbadin, go to the INN to sleep you get attacked by the Thief, a very short lived combat ensues and Mr. Grimm comes out and thanks the MC's party for finding him. After some dialog he suggests you visit him at his camp site. (Also remember you have the deck of cards, found in 'Key Items' and you should have a sleeping roll (or bag). That can advance the time as well.
To be honest the game should have a walkthorugh, since the only quest your made aware of is the Dungeon and the bulletin board at the Adventures Guild. In fairness any RPG game always requires the player to find quests, talking to any and all NPC's outside and in buildings (well the buildings your allowed to enter).
After you get all three Guild quests completed there's a women standing outside who concerned about her Pen Pal, she asks you to find out whats going on. I believe you can only do this once you reach lvl3 (since I tried a handful of times to enter the Cawic City only to be told I need to be at lvl3.
As far as the food delivery, I was able to advance the time into evening/late afternoon by using the sleeping bag, went to the INN and got the package. I tried to this during the daytime or morning but the INN keeper said she had no idea what I was talking about. So you may also want to do the Medium and Hard missions before trying to talk to the INN Keeper. This appears to be a repeatable quest you can keep doing which can help you to build up more gold/money.
Something else if you want to gain extra lvl's, once you take care of the Thief go to Mr. Grimm's camp he'll sell you some interesting potions, one is a purple poison . I went to the Dungeon to face the second Boss, after beating him, he re-spawns and you can face him again, I went from lvl 3 to lvl7. I was using the purple poison on the Boss and his trolls.
As far as the boulder monster in Cawic I built my XP lvl to 7 bought the purple poison from Mr.Grimm and kept throwing those at him I was able to defeat him.
After the MC gets to level 5 he can now take 2 attack turns before the girls get their turn.
