Also, someone else mentioned that there's no truly "good" ending. I had the idea that, if you win the Sandbox ending, Ethan should be able to choose whether he remembers the previous game. From there, he can choose to stop Mark and Caleb from starting the game. Maybe Ethan then destroys the game before anything good or bad can happen.
Idk, just an idea to satisfy the masses.
Also, I updated the bug report.
