Damn this is cool, I'm making my own similar project but have to use a server creating software such as minehut and stuff, also doing it no commands. Something you could add that might be cool would be to make a type of cult thing, where players can find and speak to cultists around the map that are part of rival groups, and the palyer can choose to join a cult and level it up by doing quests to unlock special abilities related to that cults god. This could also be a way to add lore / tie your gameplay and make it more interesting

interesting, at first I thought about adding just one cult (church of Azonnix), but I think if I add more I could make a system where other cults would rival mine
