Quick 30-day update:
Updated the translation to game version 2.8.2. There's quite a few bugs when transitioning to English text, so I'm mostly working on resolving those so that the game is actually playable.

I'm also writing up a guide on how to fully complete the game, so that will be included with the translation. I've included some example screenshots of the progress:
