Hi Jaycee, to answer your questions:
1) Turning the game into visual novel needs more visual drawing efforts (require a team for extending project with another team). It's doable but will extend the project duration (consider this alr took one year plus).
2. The grammars already proofread by senior member who was from editorial team. However, if the grammar still needs improvement, we can assign existing member to proofread once again.
Thank you for your review and understanding.
