OK, it depends on how you put it. With the new information, maybe the question of Tyson presence isn't as much of a cliffhanger as I first thought. On one hand, it wants you to continue, to see what happened in the end. On the other hand, it's like the option with Sal. If you want him dead, he will kill himself. Or will he? Now we now that he WILL kill himself but before the update, it wasn't a cliffhanger but yet there was that feeling of you wanting to know Sal's presence even here. So I guess you're right.
Yes, I've played through Day 14. The ending could be a cliffhanger but for sure isn't a one. Yeah, the characters reference the next day as „a hard one“ but there's no proof, no event or basically anthing else that clearly concludes the day with information yet to be clarified. It's just emotional but reassuring that there's still HOPE among the group. Right?
