>stuck in the "re-introduce"
There is a way to disable that. Here's what you can do:
1. Go to the mailbox outside of your cabin
2. Type in:
developer
3. Press enter and you get the test menu.
4. Press the "Time reset, now I can't talk to my friends" option and it should disable it.
>scenes that can only be acquired in the first loop
No, eventually you should be able to get every scene and if you missed one, you can get it again after time loops.
It's just the Re-introduce phase that's preventing it right now.
