Oddly enough, you can re-watch scenes! Check out the computer. I think its the top-left icon? Any event that would be considered “non-repeatable” can be found there.
Regarding the setting to see the changes real-time; I don’t know if that would be implemented. I’ve seen games where you can see the stat change based on a choice, and if nothing happens then you just back up and change it to a more positive choice. In my honest opinion, it kind of ruins things when the first choice should be your final.
I’m not saying it won’t happen during maybe a final build. Something for people that have already played through, but it’s just not something we want during development. Great suggestion though!
Thank you for the kind words, it means a lot.
