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.

You know, now that I'm getting the hang of these, they're actually pretty fun to make...

Rules - Polycubeous

Polycubeous is a three-dimensional version of polyominous.

1. Make a three-dimensional grid out of the two-dimensional ones by stacking them on top of each other, with the grid on the top being the top section of the 3D grid.  (The example puzzle is a dome when stacked this way.)

2. Divide the grid into polycubes.
3. Each space in the grid will have a number in it.
4. Each number must be in a polycube with that number of cubes.
5. No two polycubes with the same number of cubes may touch on any of their (square) edges.
6. A polycube may contain any number (including zero) of the numbers originally given.
