Yes, it includes all the previous updates.
sir hats off to you this game was so incredible that I had to make an account just to type this comment here and congratulate you for your hard work. By the way will all the characters have a solo ending or is it only emma. also is it a true harem or just a pseudo harem where you love all girls but end up with one ? but again hats off to for your creation and wishing for the best for you and this game
