I have a suggestion regarding interactive gameplay. Given the current focus on keyboard controls, I think adding ‘mouse-based touch interactions’ would be a great feature.
Imagine being able to touch a Zoi’s hair using a mouse-click combo. The response could be tied to the relationship level: positive reactions for friends, and negative reactions (like being offended by a personal space invasion) for strangers. I realize this is a complex feature that would need a lot of development, but I think it would add a great layer of immersion for the future.
