Very nice. The wheel menu interface looks like it might be a tad awkward, but I like how the rest looks. By the way, though your other site talks about changing up the graphical style, I do like the tiles being muted and dark. One wouldn't expect a dungeon to seem bright and cheery, after all.
If this came with tools (or at least the ability) to edit my own maps and script quests, I'd seriously consider paying for it.
