I'm not sure exact numbers since I'm not on the art side of things. But I can tell you that the animations are likely the most costly and time consuming. We decided to wrap up Casino by adding 2 animations (1 for each girl) and some games, port to android, then take that time and money to fuel future projects.
While its possible we'll revisit casino later, this was my first project working with Annue and Friends and I would like to take my lessons learned and create something new.
if you want more animations check out @Star_Rifle02, he made all the animations and we'll likely work with them again. Also consider supporting us through the substar a little bit goes a long way.
