Z-levels ain't happening any time soon if at all. The thing is the game was a set up as a 2-d game, adding z-levels would mean a rewrite of loads of code that suddenly does not suffice anymore when you add another dimension to the equation.(which also mean making a mod that does this is an equally daunting challenge)
