I am not worried about anything, for me this game is an escape from real life worries so there is no way I will waste energy worrying about a game when I have a million things to stress over in real life.
I don't have a tablet or smartphone, so I'm a little concerned about the inability for me to use QR codes. I guess I have to get better at drawing designs myself, or eventually get a tablet.
That's really it though. This game is looking great.
