Hi Person!
1) On our Discord, there's an Events tab on the top left of the sidebar where you can find the times and themes of the streams and you should get a notification on when I start if you click "interested" I believe.
2) Not visually, but there's been comparison in dialogue already between MC and his father, Paul. I wouldn't 100% rule it out, but I also don't have any current plans for a scene like that.
3) There is no way I could add Leslie and Cass' mother into the game without it becoming a huge thing and basically needing H-scene content. This feels like trying to find a loophole to get me to add her haha - we don't have any plans to add new, non-NPC characters we haven't already planned for.
