Compact Claustrophobia is a Minecraft FTB (Feed The Beast - not the being angry one, but the custom challenge map making heavy use of mods) modpack. Its premise is based upon being stuck in a small bedrock hallway and entering a 3 by 3 by 3 room. In this room, you craft materials to create larger rooms (5x5x5, 7x7x7, 9x9x9, 11x11x11, 13x13x13) and automate many tasks in a heavily modded playthrough. The player (in an ideal playthrough) eventually gets access to a bedrock pickaxe to break the bedrock chamber they spawn in, and continue to progress in the Overworld (if they wish to) and beat the Ender Dragon by use of an "End Cake" that teleports you to the End.
Compact Claustrophobia is a Minecraft modpack based on the Compact Machines mod that allows you to fit rooms inside a single block.

I finally got a Nuclear Furnace in early-game Compact Claustrophobia and it is like 70 times faster than a regular furnace lol
If you don't go the way of automation in Compact Claustrophobia, you will go through a long and hard slog of manually grinding (or macroing if you're into that for some reason).
Compact Claustrohpobia without Click Machine is like doing pushups on your knees, it just doesn't work out
