My primary world, home of the original Glass Island and Skyrail system.
My modded world, featuring the delightful 
Super Hostile - 
I tend to fall off things, often. It's not a particularly good trait with this type of map, where any fall is almost always deadly. While building a bridge between two Shelf Pines, I had to knock out some Titan Willow - unfortunately there was still a stubborn piece defying gravity and shading the ground below.
Getting rid of it was going to be a challenge, even with an uncommonly sunny day. Unlike normal Minecraft trees, most of the flora in Carnage was made up of broken bits of trunk interspersed in the foliage. Working from the top down was doubly dangerous since you have to knock out the support for the very thing you're standing on.
Judicious use of wood blocks for safe platforms was working great until I nudged just a *little* too far off my platform and... bang, I was dead. Worse, my stuff was scattered across the ground.
Skeletons. Looots of Skeletons. Still, I had to try it. Not going down would just mean a total loss of my irreplaceable supplies; compass, clock, and more mundane resources. A quick sprint down to the ground netted me some of my stuff, but I was quickly assaulted by a Zombie.
Survival instincts got a block elevator under my feet in record time, and I waited for the undead to burn in the light. I was still missing a lot of my stuff. Back down I go, for try #2. This time I built an Emergency Ascent System onto the top of a dead tree stump before making my ground foray. Cautiously descending the ladder beneath the hatch, I picked off a Creeper and made a mad dash for the rest of my gear.
A brief glance into the forest gloom convinced me staying down here was sheer folly. The skeleton horde was approaching, and I was not going to stick around!
Next time, the damn tree can just very well stay where it is.
