Ellipse 14 Cob | Roof Endless

Finally, the most legendary roof setup. 2nd ever manual but 1st ever manual without glooms and 1st ever manual with this solution

This is an extremely famous script setup that was made in 2017 by a player named 光锥维.

This setup has been theorized to be possible for manual play for several years now and I am finally the first person to play a valid solution for this setup. No glooms, no pumpkins, original setup.

Solution made by hydroxyl but I made a couple tweaks to make it better

This solution works by killing the zombonies using the same cob as the imp cob. This technique is really precise and difficult but it's rigorous and it's used every single wave in this setup. It's extremely easy to miss the imps or cob too late and hit the incoming gargantuars.

W9 and w19 aren't really solvable. I played PNdJ/PND which is the best method I could find but w9 requires gigas to spawn on row 1 or row 5 or else your ices won't reload in time later in the setup which obviously can't be relied upon.
Also, I had jalapeno reloaded on neither of the waves so I had to deal with extra imp damage on row 1 both times.

Jacks in this setup are an issue but they're not as big of an issue as I thought they'd be. I spent almost 4 hours on this setup and I lost to jacks one time out of all of my attempts. I think the jacks are in their grace period or something because they pretty much never blow up the cobs.

This is a repost and this was originally played well over a year ago. Despite the solution being made by hydroxyl, this solution is really bad to be honest. It's completely vulnerable every wave to pole vaulters on row 3 (this is fixable), ladders can deal lots of damage and there's a significant smash rate if I were to guess.
Glooms aren't technically required but pumpkin on row 4 is required so you can't play the original setup like I did.
Still, the playing is really good and remliw played this solution to the best of his ability.

Works technically but it's really really bad but that's expected considering this was played in 2020.
