I second Rockbox here, it's fucking great.

There is a new texture pack that tries to emulate Minecraft's aesthetics https://content.minetest.net/packages/bramaudi/pixel_imperfection/, and also yes the eating sound is annoying, you can easily change it (on linux) ~/.minetest/games/mineclonia/mods/PLAYER/mcl_hunger/sounds, you can find three files there, for me I replaced them with the Minecraft ones.

While in game, Escape>Change Keys> in the right corner checkbox called "Double tap 'jump' to toggle fly". For flying faster, you can press J (by default?) to enable fast mode, you can change how fast it is in the settings menu, in the main menu. This is all assuming that you have the 'fly' and 'fast' privileges.

All players should check the settings menu at least once, I changed many things in there, and you should too. One of them was enabling the crosshair in the Touchscreen menu on mobile , it enables a much smoother experience on mobile.

Funny that you mention the Pop_OS video, it was also my first distro after buying a laptop with a broken windows 8 install. I immediately switched to Linux Mint the next day :P

I used to search for DSBM, but instead I type BDSM and get even more depressed.
