I kind of see what you mean about the number of stairs, but it can be adjusted in the map really and I don't think it is a major issue.

This is awesome.

I love the shadows and dithering.

The different size and number of steps for the stairs are a bit confusing. :/

So the arrows turn white if the area is passable? Should there be arrows for the stairs, I guess that might be too cluttered though. Some games only have the arrows for blind spots or if the character is next to the passage.
