The spacing issues are a problem, but the translation itself seems above average compared to what I've seen in other Nutaku titles (minus the edits, which are awful). The Japanese script itself isn't very good though. Storytelling is not this game's strength.
In addition, the game appears to be following the original event schedule and using the updated system / engine. There's a level of technical competence, effort, and polish in the English release which seems to be lacking in the other Nutaku titles I've played.
