Finally gave in and played the game using Google Lens on my phone to translate it. Boy am I glad I did because I forgot how good at action scenes this developer is. No wonder the game size is so large, it has lots of cool action sequences.
Google Lens also did a better job than some MTLs, and I understood the story fine. Even if I wound up with a sore arm for a different reason than usual after holding up my phone for so long.
I'd play it again the moment a proper translation came out, but for anyone willing to deal with the hassle of Google Lens, I say go for it. The story is worth it, and a better translation doesn't seem likely to arrive anytime soon.
