No real person makes mistakes with he/she in written language. It's due to machine translation.I Need to point out at the start this is not criticism or is it a complaint.
I had meant to post this to help before now but RealLife got in the way.
As the Dev is willing to admit that English is not their first langue.
And this being their first game they don't have or maybe can't aford a proofreader.
Plus as translation software is still not great it is hardly surprising that the same mistakes happen time and time again.
For any Dev's who doesn't speak english as a first or even second langue if they speak it at all.
So this is meant just to help out with one small issue in this great game.
And just a guide for finishing this game and if this Dev intends to make more games after.
I can't offer to proofread as I'm not great with spelling and grammer even for a Native English speaker.
Nor do I have the time but the only advice I can give is this....
In English when you talk about or are talking too a Male character then you should always use the following pronouns....
He, Him or His.
However when talking about or talking too a Female character then the pronouns are always...
She, Her or hers.
Again this is meant to help and is not either criticism or complaint...
Hope this helps.
Speech is a different thing as I know personally. No pronoun mistakes in English for decades but plenty in Swedish... It doesn't help to learn them in one language I guess. (There are no such things according to sex in my mother tongue.)
People who only speak English seem to have difficulties understanding this, because they have no experience themselves.
