Thank you so much! I'm so happy to hear you enjoyed the demo and that the timed choices weren't a bother. And, yeah, there's definitely a lot of info on the guide that you'll have the opportunity to learn.
Because the voice acting comes in starts and stops it can be a little weird since there's not the normal progression from one emotion to another, it's just suddenly there. Like with the 'Damn' example, Bemelle isn't meant to have any kind of noticeably emotional response. His strong emotions from earlier scenes have passed and he's mostly just mildly disappointed. Hopefully since the finished game will have every line voiced things will flow better.
