Well, I talked to Jay Miner on Sunday, and he said he thought some of it was
definitely dual playfield mode.  (especially the inside levels.)  I think
all of the Psychnosis games are assembly, given that they always crash on
68020 and above machines. :-)

As for the parallax effect, another friend told me he thinks it's done by
manipulating some rastport structures --- the problem is that you'll have to
take over the entire machine to do that...

The characters are done by sprites.
