I think the other response was quite accurate. Different language and architecture makes it harder. There are mods made for minetest that can work with MineClone2, so there may be some stuff you’ll enjoy, but usually they have to specify it’s available for MineClone2. Here is a page if you want to have a look: https://content.minetest.net/packages/Wuzzy/mineclone2/hub/

Minetest modding is actually quite nice to do from what I’ve heard.
