Two more versions of NumGuess have been added: the D and Go programming languages, bringing the total up to 35 different implementations/languages. They can be found in the usual GitHub repo under numguess.d and numguess.go respectively.
These are the result of random Google searches to find new languages that haven’t been done yet. If you can think of any you’d like to see that has an easily usable Windows/Linux compiler or interpreter and can make programs that run in the command line, please let me know in the comments below. Or write it yourself by the guidelines and submit a pull request, they’re always welcome.
