7: Dimensional Door Mod
Sometimes things happen that shouldn’t. Sometimes a door is not just a door. In this mod, you can create doors that lead you to a sort of warp dimension, a pocket dimension, a black lodge. Whatever you call it, this dimension is a doorway to yet more dimensions. Insanity awaits.
Actually this offers some interesting neat little travel tricks. Doors within doors, dimensions within dimensions. There even is an extra dimension deep down the well, the limbo, which the player might have to traverse when taking a wrong turn, to return to the “real” world. This mod is really neat, not just because it makes Minecraft even more like Inception. Download it over here!
