and TL 0.5 (or 1.0, who knows) will cover the upcoming DLC as well as more coherency, readability and maybe a few more translated images.
Overall though, the game has been playable, start to finish, since the very first version of the translation, which only had a few scenes still being in japanese. Since that first release the updates have been improvements of the translation, and as of the current version, I don't think there are any scenes untranslated (even if some are still MTL garble that will get stomped out).
I still have every released version of the game backed up, triple so since I had a data loss at one point (even have back-ups of the Demo A.K.A Crazed Translator version still, which is weird to play as half the game is just... not there).
