Puzzle 58 - Polycubeous 3

Hey, it's me, Polycubeous!  Remember me?

...so, I had this idea of making a two-layered Polycubeous puzzle a while ago, but when I started doing it I messed up really badly.  I recently decided to try again.  Now, I have created a masterpiece monster.  This puzzle is insanely hard.  I usually hate puzzles of this difficulty, but then I ended up making one by accident.  Oh well.

Oh yeah, also, the solid gray lines are there just as a reference when you're in the more middle parts of the grid.  They have no relevance to the actual puzzle whatsoever.  There are only two levels to this puzzle.
