Hi, I'm glad you like the update c:
Here's answers to your questions:
1 - Not yet
2 - That fight is just me testing combat, it's not in the game
3 - There are currently 2 scenes with Kris
4 - If you don't sleep you get "sleep deprivation" quirk and that makes you slowly lose XP. If you lost everything at once that's not supposed to happen.
