Well the game is playable.
Translation wise, there will be weird translations here and there.
I've made this release with the naming style of when it came out along with the Viz release of the manga.
The difference when i go v1.0 is that i'll change the names to what the modern re-releases did and make a double release.
That way everyone can have their preferred naming style.
Like said in the topic start:
With this release i also changed the character naming style to the Viz release (time appropriate) So Gally -> Alita, Ketheres/Tiphares and Hugo.
I'll probably be making an updated naming convention for the modern naming as well (not that hard to make). Alita, Jeru/Zalem en Yugo. (modern kodansha naming style)
So if you can't wait, just play the game.
The translation will probably not get any better without actual JP-EN translators.
Just the obvious bugfix here and there.
