I've only seen it on the Eng site now.
I downloaded the updated version off the Jap DLsite last night, and it works. I DID have a problem getting an updated version of another game that was supposed to be updated the other day, but I gave it a day or so and then it had the update included. Perhaps it's just a glitch then?
Onto the update for this game, while perusing the gallery, I noticed that the giant worm actually has more animations than I saw in the actual game. In-game, if your health went to zero, nothing happened and the animation was sort of glitched and her clothes was in a perpetual loop of disintegrating every so often. Whereas in the gallery, there were animations of her clothes fully going away, and then she was sucked deeper into the worm. Though there's another glitch with the ground worm where it will show you the animation of her going deeper into the worm towards the ground, but then it plays the animation of her getting sucked in more upwards, as if the worm from the ceiling had eaten her. It pains me to say this, but man there are still a lot of glitches that I'm unsure the author knows about. That, or they plan to fix them up in a content update that'll happen in, say, a few months from now.
