Regarding the translation timeline: since the game development is handled entirely by myself, and I'm currently overwhelmed with my main job, I simply don't have the bandwidth to work on it as quickly as I'd like. Unless I can find reliable help with the translation, the English version will likely proceed very slowly, and I sincerely apologize for that.
Furthermore, I don't have a proofreader for the English version, so any errors in the translated text cannot be detected and fixed in a timely manner — and I'm truly sorry about that as well.
