If anyone's interested in this sort of puzzle, the game Noita is filled with them. A large chunk of the code's in lua and you can inspect it!

The final puzzle for the game is a cryptographic puzzle that's been unsolved for five years now. Folk have done just about everything imaginable to solve the puzzle.

This is a great real world example of where leetcode is useful.

One of the nice features of one of the mods I've used is making bedrock one level thick, and flat everywhere. Feels nice to me.

Interesting problem.
