Hi Chris,
Just received an email from someone called Peter at xxxx&xxxx@gmail.com.
He had some concerns regarding returning to previous chapters.
Initially he ran into issues with the game remembering actions that were yet to occur in that iteration of the game.
Then he said the game prevented him from accessing previous chapters.
Even attempts to start a new playthrough wouldn't work. He said the program would crash and on reload brought him back to his current chapter.
Because he's not part of our playtesting team we suggest you get in touch with him directly.
Thanks,
TL.
