This project uses a user-provided seed number to procedurally generate a massive network of rooms for the user to explore. This means that two different Scratch users on different computers will both be experiencing the exact same "world," as long as they enter the same seed. I haven't played Minecraft but I understand they use a similar seed system to allow different players to explore the same Minecraft worlds. This came about while I was trying to make a mini-map for a game I was working on, but never ended up making the actual game or overworld, just the mini-map. But I think it's still fun to just explore the mini-map. Be warned, load times are pretty intense. I usually just set the world size to 500. I don't remember which of the five artstyles are cool and which ones are lame, so try them out & decide for yourself which one you prefer!
iirc this project uses an adapted version of the Wichmann-Hill pseudorandom generator algorithm, I don't remember for sure, I may have used my own simplified pseudorandgen instead -- I'll check later to see for sure
