i imagine they can be changed, however, im not useing the console. i couldnt get it to work, due to useing operaGX instead of a normal browser. i had to have the widget, and apparently quite a few of the options availible, dont work.If you are interested in how the console actually works for Twine/SugarCube (this game's engine), this site has a tutorials section for that, you can check it out.
For this particular game, search this thread for what you want to do, or just search for 'console'.
Changing the stats of your NPCs is a thing that you can in fact do.
perhaps it has been updated recently, or there was something in the game preventing it from working that may ahve been fixed. ive been pretty busy for the last few months so i was unable to play.
