Copying our reply to your DM over here - Yes, and we think it's fine so long as the translation is considered unofficial and the game remains free for everyone to play. If you have any questions about the text and what something may mean or intended to mean for localization, let me know and I (gyrium, the writer) might be able to help. You can send me a message on Bluesky or send me an email if you prefer.
