Make up your mind if you want to search everywhere yourself for little hidden stashes (mostly gold, but also some goodies) or not. If you want the stashes to become a shiny thingy on maps, then search the first map outside town thoroughly and find the "detector". Once you found it, you can not get rid of it again.
combat is mostly normal,
extra hint: do not leave for the big town before you made friends with the dog (they join)
Since the game is mostly about finding things out on your own, that's all hints I am comfortable to give.
Takamakuran's other games also have this gorgeous art, but they are weirder, more WTF-is-going-on-here.
------------------
and there is The Last Sovereign. rich in lore, gameplay, characters, ...
combat is mostly normal, but extremely well-tailored to players strength (finite amount of XP)
and the other
Sierra Lee games
---------------
and Eiyuu Senki - World Conquest (GOLD is a second game, you should play after world conquest if you liked that)
I hear the game engine is actually google chrome/ium so it
should play fine outside windows?
