I like the fact that the dungeon floors in JADE are much, much larger, since the old 80x20 restriction is gone, but right now the room creation algorithm needs some serious cleaning up. The number of parallel corridors is way too high and there's not enough large rooms, the biggest one I've found was about 8x8 or so. I'm well aware that we're in early alpha, I just want to get this in rather sooner than later.
And one other thing: It would be very helpful if there's a way to find the stairs again (apart from just walking back to them). I've spent about half an hour crawling through a dungeon floor on the desperate search for the up stairs. Zooming out only helps so much, going any lower than 4 makes the screen barely readable and amidst all the dropped items one small < gets hopelessly lost. Maybe either a button combination that tells you "the up stairs are in the northwest" for a general direction, some kind of highlight so they can be seen when zoomed out far enough, or - I'm hopelessly spoiled by Stone Soup in this regard - a targeted 'w'alk option. Hitting w> for example would move the PC to the down staircase, but I can see all kinds of trouble with pathfinding code creeping up, not to mention when there are multiple stairs on the level.
Barring that, a pickaxe in 0.1.3. would be very welcome, to tunnel where no one has tunneled before. I'm really, really sick of having to walk 45 spaces through three rooms and four corridors when all I need is ONE wall segment out of the way
Since the scope of JADE is much larger, what are you guys thinking about recall magic (think Diablo's Town Portal scrolls/spell)? Would it make the game too easy/exploitable? What about long range overworld travel in general? Will there be a way to get from town to town in a speedy manner? In ADOM, the real estate one had to cover was fairly limited, being about 75x20 spaces on the overworld map, but with multiple screens in every direction, food consumption, time and whatnot, alternate modes of movement and ways to keep tabs on one's position would be definitely things TB should look into.
