Minetest speedrun concept: Obtain diamond

Since there's no Minetest page on speedrun.com, and almost no speedrunning footage for this game I decided to make this little concept run. It's just a little showcase; not a serious run, I was too lazy to put a timer on it. The hypothetical rules for the category could be: generator v7, random seed all the default generation settings, and gameplay performed on non-creative with damage on. I was playing with debug info off, but it could be allowed. Timer should start as of starting the gameplay and end with obtaining a diamond item. The game should run unmodded. Obtain diamond was one of the first categories in pre-release Minecraft. I thought it would be natural candidate for this game's speedrun target. Minetest has a lot deeper undergrounds and more challenging visibility range. That requires planning both amount of food taken to prevent death and coal collection to see in the darkness.
