The English version definitely has typos and grammar issues, but mostly it's missing a lot of punctuation.
Autosave would be nice, especially since it's super easy to set up in MZ. I also had to replay the first part of the game due to the fall.
I did end up solving the crystal puzzle, but I'll admit it's not super intuitive. I then finished the Aries puzzle, or at least I assumed I had: I ended up back in the hallway and nothing had changed. I went to the first room again and the statues had returned to their place (Ino's statue wasn't there anymore).
So yeah, I got stuck.
The art was very nice though, good job on that.
