I've been playing rogue like games for years now, and I can tell this is one of the BEST.
It has a perfect battle system and well built skill trees.
Something that I would like to see is a town, some NPCs and a story mode somehow.
And also an HD version for steam, different clothes for the mages, etc.
So far it is PERFECT.
I bet the game for the first time after a few days, around 30th try. The game is hard, but it is fair and worth it.
I'm buying steam version and hope for improvement (if is there something to improve...because it is already awesome!).
