Yeah I've asked myself the question what should be the most frustrating warpzone, and it is *drumroll*
MMMMMM. I know it is piss easy once you get the hang of it but god the warp zones hurts my eyes! Who could imagine that those happy flashing squares at 1-2 are so violent?

The Skyscraper ain't to bad it's the most challenging one. As in it's really skill-dependent. 1-2 is not that bad once you get the hang of it but god you need to do the whole stage again if you collect the bandage and I often just hestitate to much ending up losing the level. I can speedrun 5-1 (well kind of) really much and 1-3 is really easy but once you got to the last part where you have to gap through those spikes and then either decide if you want to go left or right is really annoying.I have yet to get the bandages at the skyscaper.

So what is your personal most annoying warp zone?
