I was very curious about this game, but I am only a couple of screens in and the dialog includes:
"I'm a hotel in a small state near the largest desert."
Writing in a non-native language is hard. I can't imagine if I'd be brave enough to do it. But if you are going to do it I suggest trying to take advantage of some the tools around right now. Ideally (of course) would be to get some volunteer editors. Lacking that...
* Grammarly (there's a free version) grammar checker
* Bard (Google's AI chatbot, also free, just ask it to convert the grammar for you piece by piece)
* Hemingwayapp (free online, suggests reading level too)
And there's other free stuff. Maybe put the text through those tools and let them help make life a bit easier. Especially at the beginning of the game, where folk decide if they'll continue or not. Good luck!
