I agree that none of the games in Minetest have anywhere near the level of polish as Minecraft. And as we’re comparing a pretty niche game engine built on by hobbyists vs Microsoft, it’s very much to be expected. I also agree it shouldn’t be recommended as a Minecraft alternative.
But the from the first half of your post I think you misunderstand the point of Minetest. Its not meant to have an overarching game design. It’s a game engine. Its designed for people to use to make their own games.
I think it is on android still? In which case I recommend megladon. It’s a fork of the official app with more features, like following hashtags.
I thought all the third party apps were really ugly, so I was happy to find out about this
