That tower is awesome as hell. I wish I'd built anything that cool. And man, it must suck if you accidentally place an obsidian block in the wrong spot...
It wasn't that bad. I think I misplaced about ten blocks.
Thats only 150 seconds of additional "remining" time.
Then again I had built the entire tower with cobblestone first in order to get the shape right.
After that it was just a matter of replacing each cobblestone block with obsidian.
What you see is actually the "second draft". The first tower was almost twice as wide and I realised midway that it would have to be way to high in order to get the proportions I wanted.
Thankfully, tearing down cobblestone and restarting from scratch is way less tedious and rage-inducing as tearing down obsidian.
