Answer 1

I don't really see how these are much different than normal v-ceilings.

Answer 2

Yeah it's just more precise inputs because of them being one tile and the spike jump right before.

I'm not too sure what the obsession with this "tech" is, I don't think people are not playing those maps because they can't do the tech. I think it's more because since it's pretty precise, it's frustrating to have to do that many of them so people don't want to bother with those maps.
