This might well be the explanation here. While under Android the game tries to compensate for weaker system specs by reducing graphics quality etc., under Windows it runs at the highest quality setting by default. For a convertible like the Galaxy Book this might be a bit more strain than under a desktop Windows setup. Unfortunately there isn't really a workaround at the moment other than maybe trying one of the lower resolution settings.
thank you for the feedback, Really am looking forward to the full release of this vn. it is really unique and stunning from what i have seen.
