Freemium tactic in a premium game

Bought this for my son (10 years old). This game was developed with a rating of ages 9+, but requires you to link to a Facebook account to be able to use all features (saving, leaderboards, etc.). But Facebooks terms of service require you to be over the age of 13 to create a Facebook account. I could see crippling features like this in a freemium game, but not in a $6 premium game.

The graphics are spectacular but if you are using an iPad the gameplay only takes up about half the screen and the controls are way too small on an iPad.

Because of the crippled features well be requesting a refund.
