've been thinking in some game ideas (Patreon)

What I had in mind so far was multiple sprite sheets the player would fade into for a slow digestion progression
But that would make it look like anything Pherl eats just dies immediatelly, just now I had the idea that there could be 2 types of sprite sheets for her: full with something living, and just full
But that would create other issues, like, there are a smooth progression between full and slim, but if she haves something moving inside she would need a variation for every belly size and prey's state

I also thought that prey stopping movemet could be an indication for the player that she can spit their bones and skull now

I do like solving this logic issues myself but I wanted to see if you have any idea
