It's definitely good that you want to be improving your English grammar and writing skills, but how exactly do you plan to do that without help? How will you find all of the spelling an grammar errors without a proof reader? Or even more so, how will you improve your English writing skills (like a natural flow of words and believable vocabulary) without the help of a native speaker? I am not offering to send you fixes for you to accept without thinking. I am offering to support all of my changes with explanations which you can read so that you can understand why the suggested edits are an improvement and learn going forward. Additionally, if you would be comfortable with it, I could talk with you in a voice call and go through and explain any writing suggestions or even help you with writing ideas on how to best present whatever story you have planned. I don't consider this any significant use of my "precious time" since I don't imagine it would take much time anyways. With you taking 2 months between V0.1 and V0.2, I don't imagine that there would be any need for us to have extended conversations more often than something like once every 2 weeks, and its not like the meetings would take all day assuming you do go along with doing the voice call thing as well. I do agree that you should be getting better at writing yourself rather than relying on someone to fix it for you, and the help I am offering is intended to make you a better writer (in English). I understand that this is a passion project for you, so if you still don't want anyone else involved in it than that is fine. My offer still stands.
