You are asked your child's first name and age, what is hardest right now, what they actually want, and the one big thing they keep asking for. From those answers the app builds their buttons and their prizes, so you never have to invent a system from nothing.
Your child then chooses their world — the theme their board is drawn in — and names the companion who cheers them on. That is the only part that is theirs to decide, and it is worth doing together.
What you can change later
Everything. Every button, every prize, the name, the age and the companion can be edited afterwards from your child's page. Nothing chosen in the first two minutes is permanent.
