my thoughts, being the first time i actually finished this
it seems like i stand alone here, but i'm not overly impressed with this. it's got good use of COs and such, but it has no flow to it. the tilesets are all over the place, going immediately from realistic to meh, and many of the scenes just look lazy and messy.
there was obviously a lot of work put into this, but it seems like that work went into how big it was (quantity over quality). and this is partly my ignorance, but i couldn't really tell when (or if) any of the tilesets were custom, as it seemed like i'd seen them all before.
now for the plus; it was very big, and there was a lot to see (i've still only seen part). it's impressive to see that just one person did this. the music was great. the challenge was just right.
still, when levels become this big (i'm looking at you, Gaia), quality becomes sacrificed for quantity. however, as this level's popularity suggests, quantity is great for many people; i guess it's just not my taste.
this level is definitely quite the achievement though.
