Ideas for a sequel if anyone is still interested in the show/wanting to give it a shot.
Manehatten falls under an outbreak of a viral strain of Swamp Fever. Octavia, Vinyl, and others must survive as trees envelop the area and ponies infected become mindless, deformed carriers.

That having been said, I'd be interested.
It looks like a good base idea, but maybe it needs something else to spice it up. Maybe some mechanic or a twist on the original "zombie" idea. You did with OatUC by mixing magic, afterlife, horror and surrealism with a good argument and a sanity indicator (plus, the many sprites sure don't hurt). Octavia felt very real in there.
I'm not saying its a bad idea, just that it might need some work to flesh it out.
