MyFSharpSnake is my attempt to exercise some cool, fancy Functional Programming, using F#. Initially a terminal program, I made with (some sort of) ease a webapp using the already-made game logic. Honestly, that was an interesting exercise.
You can check out its source code at https://github.com/ALEX11BR/MyFSharpSnake. The app is available under the Unlicense, so basically public domain.
