Right, so this deserves a little bit of elaboration if you're not already familiar with Haskell. Haskell source code satisfies a substitution property that source code in other languages doesn't. In Haskell, you can take any common snippet, refactor that out to a name, and invoke the name instead, and this doesn't changes the meaning of the program. Similarly, you can inline any named snippet at its invocation site without changing the meaning of the program. (Here's a good explanation of the substitution property I'm talking about, along with a demonstration of how Python, for example, does not satisfy the same substitution property: https://github.com/tonymorris/fp-course#demonstrate-io-maintains-referential-transparency.)

In COVID I polished and released my Python implementation of the game which I actually did years before the Haskell one, mainly because it kept working while my Haskell implementation bit-rotted due to my choice to use the library GLUT which has since stopped working.
