Set up is terrible & confusing

Ive NEVER given a BAD review. This app may be fine for much younger children- but the "add on pacs" are confusing - and I feel are intentionally misleading. They list them (supposedly) ale-cart w the option to buy "packs" I bought a 3 pack- which I thought i could choose what i wanted - not so ! CHANGE YOUR FORMAT.
I know I do want my money back.
