Yo!!!! I've been checking in every so often so it's great to see you're doing good and making progress. I'd like either voice option, but I realize the beeps would be easier to implement and customize.
Also, there are lines when the character is poked or interacts with stuff while full, where a burp or other sound is written into the dialogue but no sound plays because she's not being fed. Even if you don't go fully voiced, would it be a good idea to make some dialogue play the burping or belly noises that are already in the game? Like what if we could hear her belly sloshing during the exercise dialogue?
