Currently the game is supposed to end when you go to sleep in your dorm room at the end of day 2. The error from before was because it was trying to pull day 3 which was not in the game. I fixed that so now it should be sending you to an afterword where the "dev" is talking and then you will go to the main menu.
The new character can be met when Silas doesn't give you a ride at the beginning. To achieve this, your charisma score must be no higher than 10. Basically during the orb questions, don't choose "love", "lover" or "friends" and you should be put onto the new content path.
