There was another release in the NumGuess family recently: S-Lang script. I’m still looking for more implementations to add, if you have any ideas please contribute or let me know and I’ll write it.;)
The guidelines have been updated too to make it clearer and stricter. Language limitations must always be mentioned in the README and programs cannot be conformant unless they satisfy all requirements. Non-numeric input must be handled correctly, run-time errors are no longer allowed. Proper variable names are also being enforced.
The above changes made a few programs non-conformant e.g. Pascal and QBasic versions, they might be updated in the future to fix.
