It does make sense that to really sell some personalities, they should work differently from others. For example, the sneaky feeder feels a bit constrained by the game's systems to really deliver on the secret fattening theme.
The personality-focused update will include special personality-specific scenes to try and address this and help flesh out who they are more. So, whilst I probably won't be introducing a complex kidnapping system or similar, I'll definitely try to make the yandere personality feel like a real yandere with special yandere-only scenes.
I've had a lot of requests for trans content & this same update will also add both male characters, trans character creation options, plus the ability to transition within the game itself. All of these will be optional features for players who want them.
I'll keep adding more and more personalities over time, but with this particular update, I plan to include the 6 highest scoring from the poll, plus a dominant feeder personality, a new feeder personality and 2 mutual gaining personalities.
After the final update I have planned is done, I'll probably keep going!
