Great concept, poorly executed! Apparently the game is designed for only one user and you can’t have different games moving at a different pace for multiple users unless you sign up with different accounts! I spoke with them directly about this and that is the intended design! Sooo if you only have one kid using it, then this is for you, but if you were hoping for multiple kids to be able to use it and it save where they left off then you will want to pass on this one! It’s a shame, I hope they change that at some point, but when they emailed me back it didn’t seem as though that was a plan and that it was intended for only one kid per iOS account.
