bah actually i finished it after about 50 minutes (thanks to certain annoying enemies that forgot they are supposed to die)
here is what you should do:
a. get your ass above the starting point, 2 maps up there is that knight guy, he will join you
there is also a new rabbit there that will full heal you
DO NOT FIGHT ANYTHING
b. go back down and this time go west, you'll see a guy and next to him there will be a hole, you'll have a healer down there
you'll also see a monster that can kill you too quickly, that's why you got the knight , with him you don't have to worry even if that annoying thing decides the healer shouldn't live
somewhere around the north you'll find the mage "omg there is a monster in the well" kill the silly thing and you'll have 1 big fat omg useless mage, the only good thing about her is that she is a really good punching bag and it helps when you don't want the main hero, arshes to get killed
around the maps you'll find a rabbit, it runs quite fast, lock him in a corner and you'll get nice gold
do it over and over again until you can get the best equips
put them on and go to the bosses castle
kill the annoying and refusing to die mages.
get in and buy full healing potions, the sp+hp type
buy loads of them
can't buy? go beat up the rabbit
oh wait did i mention you need some training? heh silly me
near the rabbit there is an area with the monster you killed to get the healer, it's very very xp profitable to kill it again and again, it's easy, it takes 1 turn and it's good
level there until arshes get his 2nd skill, it's a nice stunning thing
go back to the bosses, and use basil's leg sweep and arshes's 2nd skill all the time
fear not ! the monsters go solo, seeing as you stun them, you will win at some point , don't forget to use the potions if you run out of sp
and.. that's bout it
