All's well. Logged into my account on my dad's iPad, bought the full game, and all those options are unlocked on my iPhone as well. What tripped me up, though, is the game's store screen has a "Restore" button in the upper right, but it's covered by a friggin' banner ad. (The game's free to download but it's very limited, gives you ads, etc.) I was freaking out wondering why my $12 purchase wasn't showing on my phone even though I'm using the same Apple ID. Thankfully saw the "Restore" button on the iPad and was able to click it on my iPhone after some fidgeting around.
Bah.
It's more fun on the iPad I'd say, just 'cos the screen's bigger and all. Although tilting the iPad to move left and right can get tiring on the wrist, though resting it on a leg and tilting it then seems to work well. But it's cool to be able to play it on my phone also.

Time to go do some iOS gamin'. (In addition to Zombie Panic, I bought the two Ghosts'n Goblins games. Likely will be buying more, like Predators which looks pretty sweet. Man, havin' a smartphone after all these years is pretty kick-ass.)
