After thinking it over for a decent amount of time, I decided to make the plunge, and make a whole Minetest game based off of floating islands, as brought up in my skylands thread.
So, apart from the obvious implementation of skylands throughout the whole world-space, this packages numerous mods from the forum in the base game, with the goal of streamlining the sky theme and making it easier to get things done when huge voids separate the lands. These mods are:
skytest_init, which does two things: Force the mapgen to use singlenode, and generate an island a short distance below origin to serve as a safe starting place. The island is a sort of bowl filled with water so as to cushion the fall of any player. Picture:
Now onto the specifics of the game itself. When players join, give_initial_stuff is active by default, although here it only gives 99 torches, one steel pick, one steel shovel, a steel axe, 99 cobble, a bridgetool, and one helicopter. The torches are there to help when islands shade each other (which is very common). This game runs in parallel with my development of skylands, so usually any updates there follow here shortly after. Eventually, I would even like to add a goal to this game, potentially finding some sky temple or slaying some dragon (or both). But that's still a ways away.
Now, for the proper things:

Unzip in the games folder of your Minetest installation, and rename to sky-test.
