I would encourage you to go through the whole game if you could; the third day has lots of story and activity which makes some things make sense.
The choice in question is also meant to feel that way; we wanted the player to be on the back foot and have to make a reasonable guess based on background after having their hands held for a bit. We were also a bit restricted for to some development issues; our original vision was a bit more involved.
I'm at least glad you seemed to enjoy the art and acting; they're what really makes this story come alive, so the credit goes to them for that.
