Check out: The Points System
You can make them either lose or gain points (-1, 1, etc.) by writing something like:
@MC +1
For when a positive choice is selected.
or:
@MC -1
For when a negative choice is chosen.
Or you can even create two new characters and name then anything like GOOD, BAD and make a point systems category based on that. So, if they do bad actions, they gain BAD points, if they do good actions, they gain GOOD points.
Hope it makes sense what I’m trying to say ^^
