NOTE: Don't expect this to work as it is in alpha!
I have made a mod that adds different types of herobrine, adds ores, and adds new items! Some features of this mod include: more herobrine mobs, more ores, more items, etc. I am working on this mod daily so I hope I get enough updates regularly. The intended use isn't for making horror movies or something like that yet because I am not sure if it would be easy to make one with this mod, but the intended use is for playing around and see what happens!
