There was an error that prematurely ended the game in chapter 5.Did the game change and that is why we have to start over?
If that is the reason, how much did you change? renders/story-wise?
It's been a while since I played this so I don't really mind starting over.
Thanks for sharing.
I also added new labels for the replay areas in the earlier chapters. Those will be unavailable until they have been played.
It seems some people are still able to play with old saves. So try an old save and see if it works!
