hexagony VS AoC2020

It's got a larger symbol set, but it's still relatively code-like. If you want some obtuseness, try out Hexagony where you code in a hexagonal grid, using a hexagonal memory, or Malbolge, who's entire goal is to be as hard to code in as possible.

Some examples that I find interesting: * Brainfuck * Marbelous * Hexagony * Emoji

The most highly upvoted solution to this problem is a 6-character-long program written in the Hexagony programming language.

(As an aside, some people "stop" here and then make programming languages based on this - because that is a simple interpreter... you could write a compiler for this language, or extend it - and the great golfing languages take that starting spot and keep going - don't worry about trying to replicate it, it takes some insanity to go that far - the point is that a stack based language is the starting spot for some impressive systems... like the JVM itself)

How about a programming language?
