Irritating.

Always needs you to sign in.
Always boots your game.
THEN forces me to rate them?!?
I paid for this game, dont hassle me, and make this thing stable.
Still continues to hassle me to rate them.
This game is fumbling and irritating how they extort my rating.

UPDATE: 1 year later and this game is still unstable and poorly supported. Dont pay for the "pro" version. Most times, sign in wont work, game screens always force a reload if you switch between active apps.
This is a very obvious case of an Orphaned IPad app.
