Fun idea I had, I remember seeing mentions of a skill tree system and I thought about how cool it'd be to pick skills based around different feeder types. Like you could lean more into a dominant feeder type and get girls to eat through harsh dialogue options or a sneaky feeder type with sneaking bonus snacks and meals but with heavy affection loss if they catch you.
Could really make your character your own and add a bit of replay value and strategies with the build you make. Maybe even a feedee skill route for player self feeding bonuses and more.
