Plenty of times I have gone around in circles and wasted hunger due to me not seeing the one correct path, or not finding the right room. A map like the one in the original games showing what tiles/rooms you’ve explored so far would really help. Maybe show the tiles other players, enemies and items too, if possible? Of course, it would only show the ones on screen. But I’m not a developer, not sure how hard something like that would be to program.
I would love this in game, maybe triggered by a hotkey so it doesnt get in the way. This shouldnt be too hard to implement it’s just a matter of developers time and effort
I kind of like it without TBH more “mystery” dungeonish 
This is a really good idea, but I think the staff need the source code to make it happen iirc.
