I don't think I put any in the demo, but I certainly have a handful of more silly sorta choices written in some of Castor/ia's script that's not currently in the game, haha.
And yeah, the other choices for things to do will lead to other routes eventually (some are just to access other options rather than routes) :3 I kinda made the demo backwards by taking out some stuff that I'd already added to the game that I didn't want in the demo, haha. So in my current WIP version of the game, you can answer the phone call that you get at the start, and you can say yes to the trial and go straight down to Kiaria corp and do more from there, but I took it all out for the demo because it's not fully finished and wouldn't make a whole lot of sense if I left it in x3 And then the options like going for a walk and stuff trigger meeting a different character that you might miss if you chose to stay at home and do something instead. So yeah, they all lead somewhere, just not in the demo x3
Glad you like the new features and stuff anyways and that you can see how different it is compared to the old version ^-^
