What happened?

Loved the 1st game & had high hopes for #2. What happened? Although still fun, game filled w/ instability issues. Very choppy on both iPhone & iPad. Many times wasnt even able to click on anything on toolbar, forcing me to reload. On ipad, got to round where it was so choppy, could barely nav around city. Horrible when player has time limits. Paid $7 for full version on ipad & greatly regret it. Wish apple allowed refunds on non-playable games :(
