Yeah good point Suliman, I've actually built a system into the renderer so that the user can rotate the view of the world by 90 or 180 degrees to see things around cliffs.

I think a visible grid would help, particularly to solve ambiguities between height variations and horizontal displacements, count horizontal distances, count height differences (this tile is N layers above the adjacent tile). Seamless isometric graphics work well with simple natural shapes and ramps, like in Starcraft, not with stylized steps.

Alternatively, a nicer map structure would be legible without needing outlines; I don't think a regular structure (e.g. Q*bert) could be an option given the current screenshots, but maybe you can decide that the game is set on a slope (given two tiles if x1>x2 or y1>y2 then z1>=z2) to prevent occlusion and avoid having to turn the viewpoint.

Hi LorenzoGatti, adding a grid would improve visibility but make the graphics kinda ugly. Not sure if its worth it?

I've taken some extra suggestions that some people have given and integrated the mouse position into the UI.

Some updated screenshots:

Here's the new cursor in action:
