Reminded me of Diablo I - a game from 1996 I still play and love.
Maybe that's where it all fell wrong for me. Like many people have already stated, targeting system and responsiveness suck bigtime. Aesthetically, the game is also very poor. Can you picture a scary dungeon filled with detailed carving and statues of demons and skeletons, crawling with death and undead monstrosities that is also preceded by green plains, clean gates and fucking flowers? Why am I mercenary trying to gain fame and glory if I'm walking around with a towel excuse for a cape in light coloured clothing?
Also, RPG with no character customization is like sex without... sex. Role Playing Games are essentialy made to play or incorpore a role - and the more you can make that role your own, the more you'll come to enjoy it. Character classes and different styles for each class are the bare minimum to expect.
Still, the game has something to it. Maybe with some more work you could turn this piece into something very interesting.
Keep polishing it and let us see your results. :)
PS: Nice soundtrack, by the way.
