OLD school. In both good and bad ways. On standard difficulty you will be save scumming each encounter in the beginning, then cheesing your way to victory in the middle and end. Not as good as the games its trying to mimic from the 90's, particularly with combat, and the audio is repedative to the point of agony.
However - with all that said - its got a really impressive amount of dungeon maps, and its got a lot of secrets and rewards exploration. Definitly if you like the wizardy games and those of that ilk then its a good game at the price. wait for a steam sale if not.
