It's very impressive how much you can fit into 1.44MB of map.
Sometimes, especially in Mazu's larger map, it was almost too much (I did resort to noclipping around with show bounding boxes on to find out where I was supposed to go next, as I got lost in both), and some of the maps were arguably a little *hard* in Easy.
However, the actual triumph of making moderately modern-design-sensibility maps with the limits of the original levels outweighs this.
