I have agree that the shading and coloring of the rooms makes things seems almost inside out at first, but then once you look at it for a moment or two that feeling goes away. The iso-style is very interesting, I haven't seen it before and now I'm inspired to try one out myself. I like how the different levels are easy to tell apart from one another, and how you can have them all on one map rather than having to do a series of overhead maps to get a lesser version of the same effect.
