Hi,
We're happy that you like the game!
1. Yes, however, dev focuses on adding more interactions/events, cosmetics are way lower on his priority list ;
2. As far as I know - no, the game revolves around the PeepTube service, which is meant to be a place to post videos of peeking or doing non-consent stuff - sleeping assault is an example, on the sofa shed probably be awake;
3. Yes - dev has plans to add sex with Kaede first during her sleepovers, later on he plans to add other girls, but not every that you encounter will be available at night, some will only have day evets;
4. I think no - the night is quite hard as it is right now, especially when starting new game, dev will add some more nightly interactions, but I haven't seen any interruptions on his to-do list.
Cheers
