There are indeed more than one. I'd like to point out something though. For the developers who are not native English speakers, they depend on translation programmes to do the translating in English. It not only results in some grammatical mismatches but can result in some spelling issues as well. Most people do not treat it with a grain of salt and believe that everything present is correct as presented. I'm a native English speaker and writer. Even your standard word processors aren't perfect with spotting spelling errors. Sometimes, it mixes up things like "it's" vs "its" and so having an editor is a must.
I can see young budding developers who're just starting having problems accessing paid services of editors. It's why I volunteer to be an editor for some developers who're looking for such help on their discord servers. I wasn't in any way criticizing the dev, I was just spotting the issues I noticed hoping that the dev would fix them.
I appreciate you saying that and that you are willing to volunteer to help others. I would be as well and will - at some point - make that offer directly to some devs whom I see are needing the help. Not saying this dev specifically, btw.
To your point, I am less concerned with grammatical errors (like your example of it's vs its) and more about instances of outright typos where words are misspelled to a point that NO translation service would output that spelling. Even a previous comment with a screenshot showing the word "toungue" isn't a good example as that is a much older, antiquated spelling of the word tongue. Therefore, it is technically correct though no native English speaker would spell it that way.
Similarly, I am also aware and unbothered by the differences between American English and British English. When you wrote the word "programmes" above, that was correct, but every American-based English speaker would write it as "programs."
For the sake of clarification, my rant was about outright and egregious spelling mistakes. I did not catch any examples in this game but have seen some terrible mistakes in others - mistakes that NO word processor would miss.
In the future, I will try to restrain myself from any similar rantings unless I find outright examples that demonstrate a complete lack of effort to edit the text before offering the game/ update for public consumption.
