Currently in level 3, hard, old school mode. Graphics are reasonably pretty, although they could use some refinement, especially hidden doors (if you observe the bottom of the connecting walls, you'll notice that the hidden door doesn't 'slot' into a groove, but rather clips through the textures), also the texture resolution is just a bit low and muddy, I do, however, think the lighting is nice.
Moving away from the superficial, the gameplay is good fun; both puzzles and combat are too easy so far, regardless they provide some thrill and entertainment, the dungeons so far have been simple to traverse, I'm not having to map anything just yet, memory is enough for the layouts - I really hope this changes later on, as it's the mapping and uncertainty that creates the true sense of exploration.
Combat is clean and fun, spells look pretty, and it can be rather frantic to manage everything at the same time, especially if you're kiting a couple of enemies, or trying to lead them to a floor trap.
It's really good to see a modern game of this sort; so far I can see room for improvement, but I don't really care, it's the most fun I've had in a video game for a long time, exploration is simply something that's missing hugely from modern games. Furthermore I'm very interested in the future expansions and play made dungeons hinted at from the main menu.
