Love the game so far! The models look great (before and after eating) but I think that'd be even better visually if the preys didn't simply end up in the human stomach part of the lamias but in the snake part (and if the lamia eats a few characters at once, they could fill her human stomach, that could be great to emphasize the fact she is almost overflowing, since there is a limit cap of preys they can eat at once). That or after each turn, the prey go down from the human stomach to the snake one.
For now, there isn't much variations in the eating/digesting animations/stages between a regular human or a lamia eating a prey (and I understand it's still very early in the development, those are just ideas) and imo that'd be kinda neat to have specific ways for preds to eat (like having half-spider types (a bit like Quelaag but less creepy lol) eat with the bottom mouth (so the spider one) instead of the human one or slimes being able to grow their overall size when digesting, stuff like that to make each type more unique).
Again, I really love the game and I hope you'll keep working on it to create a real complete vore gacha game!
