Not sure what went wrong but you're right: the download code is X31M2MNDNE.
I also updated it again. The parallax-scroller now works seamlessly in both vertical and/or horizontal direction.
As kind of an extension of this, I made a system for serializing special sprites. They are just sprites, but with just a little extra handling.
They can't also have sprites as attributes though.
