Great! We hope you enjoy it. And to answer the second part of your question: yes. Purchasing the game now will entitle you to download the complete game upon it's next (and final) update.
I just wanted to say; you do nice work! I am not through the novel yet, but your characters have a lot of depth, and even your side characters (like people passing on the street, the park, in stores, baristas, chauffeurs, librarians, and clerks) are gorgeous, and should be in some sort of extra content or a new project! If there was an award for design and story, you'd be at the top! Some developers don't do a lot of detail on the landscape, but you really took your time with this project! I'll be looking forward to your other projects. Good job and good luck!
Some of our side girls and other cast in BW will be making appearances as main love interests in our upcoming game, Heaven's Door. You can see which if you join our Patreon (even at the $1 level) or join our Discord server (which is free!) A hint: at least one of the girls you specifically mentioned will be in HD, though we've not yet announced her.
