The art is good... But that's it.
Okay, there is no story, but It's okay, it's a flash game after all. The game is based on luck : Merchants pop randomly... You need a potion ? Na, it's a monster ! You have no gold left ? Yay merchant ! That is poorly designed. Oh, and I read in some comments that their is someone who can train you. Never met him. This is poorly designed, really poorly designed... And I'm not even talking about how unbalanced the classes are. Monk is overpowered, sorceress has healing hability, which makes her an excellent choice. Other classes... meh.
Anyway, the art is good, the idea is good, but it is poorly designed.
