Glad you're liking the game! To be honest, I'm kind of struggling with thinking about where I want to take the game next. I'm basically pretty happy with the current scale and I feel like it accomplishes what I wanted to make. I guess I'm just waiting for inspiration to strike before I add any new content.
Well i got ideas probably another world to more foods recipes even though there alot of that or probably 2 more weight gain stages can be a possibility like blob or enormous? You could add a scientists that double the calories of all foods even though the food already has alot of calories this could help if your adding more weight gain stages maybe. Hmm add more vore for all the characters even though I don't like that type of stuff. Hmm what else instead of one tavern we can have 2 more tavern with more characters or some type of restaurant tavern and it upgradeable make it more bigger you can choose female or male chef with weight gain well these are my ideas they might be pretty shit
