Essentially, it's Slimefun ported to Cuberite. Again, This is heavily inspired by Slimefun, thank you TBB!
Slimefun Repo: https://github.com/Slimefun/Slimefun4
Also, this is a hobby hobby project, as in I only really be messing with it if I have nothing to do, including gaming.
Oh yeah, and, while I would not prefer to use sqlite, I realised it's better for save data than json so... yeah
Because I am lazy, I'm probably gonna not work on this anymore. I might get back into it if Cuberite becomes an actual viable server option.
