I'm afraid there's still quite a few hurdles in the way. You can expect to play the Prologue translated soon, though that depends on if EarthDarkness finds enough time for it. The dude is pretty busy. Regardless, progress is being made everyday and if all goes well you could perhaps see the full game in a few months. Worth mentioning that the game script is in fact fully translated, the problem is just inserting the translated script into the game.
Funnily enough, English isn't my first language either. It's not really that big of an issue.
If you or anyone wants to help out, just message me here and I'll see what you can do. And don't worry, you won't need any coding knowledge or anything working with me; just a decent grasp on English should be enough.
Though if you do have decent coding knowledge, try messaging EarthDarkness instead. He's the guy who'll actually put the script into the game.
