I know I made a studio similar to this, but I'm SO TIRED OF WAITING!
The player is actually the antagonist (Plot twist!)
Noelle plays a larger part
You play as Susie or Ralsei
New realm is discovered, like the "Real World"
We get to learn more about Asriel and university
Kris decides to become a side character (Maybe)
The game breaks the 4th wall (Well that's probably what will happen anyway)
