Thank you! Part of the story of mine game was written by my brother Noah actually.
I feel you though - i'm not a native speaker myself and was pretty anxious to release a game with that much (serious) story text. I went over it for typos a lot of times and i'm quite sure i have more than one grammar mistake in there too haha.
That said, i hope you don't mind if I disagree - I think more text could have been a nice addition to the game and we all non native english speakers shouldn't care that much about grammar and spelling in this context - i rather expect native speakers to get that not everybody speaks english and that everybody should be tolerant about those things.
I at least - would not have minded a few grammar or typo mistakes if I get a got story anyway. :D
