Ohh I ge it, so the scores increase acording to which choice you choose? that's interesting, I didn't know that. I think I'll play it again.
By the way, is there a way to know how high is your score?
In early patches, Id give 0, +1 or +2 to a choice, but I realized that it was getting too convoluted so all the latest patches give 0/0/+1 so, overall each choice is a +1 if it's the right one.
The score is a hidden mechanic that can only be seen in debug mode, but that's for coding nerds and I'm not one.
