those are floors dipshit, not different dungeons
In order to be separate dungeons travel between them has to return to the overworld level, there can't be continuous connection because then it's just a different part of the same dungeon

In Diablo 1 you unlocked new entrances as you progress, each of which lead you to specific depth. Technically having one large segmented dungeon with different entrances for each depth is no different than having "separate" small ones, except that the latter makes the game simpler and gay.
