Hi Alliebee, Thank you for your post. The story is not complete yet as we keep releasing approximately one character per chapter per month. The premium choices do not impact which ending you will get in the game. That is determined by the choices you make. We also do have in-game currency sales. If you turn on push notifications and/or follow us on our social media channels, we notify you of special events including sales. We do not sell a full route though. We hope that answers your questions.
