Updating my review:
Im extremely disappointed that the new update requires additional purchases in order to play. Ive already purchased the other levels. If this is how each update is planned to be then I wont continue you using this app or having my son use it. Its a shame as I loved this show as a kid and thought it to be a great tool for my son to learn with.
I have played plenty of other "mystery/hidden" games that had an "unlock all" price (usually about $2.99) that unlocked all current and future levels/features.
My recommendation is you do the same.
I beat this game in two days. (And yes I purchased the additional levels). Just wondering when more levels would be added.
Also, the "underground" running sequence is a little spotty. It also brings up a menu on my iPhone when I swipe up to jump. Terribly annoying but not sure how to fix it. It doesnt happen in other similar games. (I.e. Temple Run, Minions...)
