Is it possible to develop for 2.5d? Is it possible to develop for games like wolvenstein 3D? 
Which uses ray casting to create "psuedo-3d" or in other words, 2.5d.

I have no idea how this would look inside the rift, with really low pixels even though that would be the point being old school and all.

I apologize in advance if this is a really stupid question!
