Hello and welcome.
My name is Sangam1. I am a fairly new modder. I have created another mod called the More Everything Mod. You can find a link to it under the overview of the mod.
The Unbreakable++ mod lets you change blocks to become unbreakable. You can use this in your server or on your own world. You can troll your friends or prevent blocks from be destroyed without there functionality being removed. Here you can find more information on items and blocks that you can get in this mod!
I hope you enjoy it! Let me know if you want me to add something to the mod!
