for the path i used the official path finding behaviour, needed a little tweaking, but works good.
with 3d perspective i still have some problems, on most scenes i set the scale using the actors.Y and a predefined offset.
but when there are angled backgrounds it's much more complicated, i couldn't get the right formula yet to set it automatically, on worste case scenario i will do it manually or with overlapping triggers.
about the puzzles game, i am checking it right now, in the meanwhile here is another link:

the file seems fine, maybe your download stopped in the middle, filesize should be 92.2MB
