Jeff, I'm sure you'll take our criticism in the constructive way it is intended. The game is great!
I found another issue today, possibly not iPad-specific. For the past 2 days of playing I've been irritated that there isn't any display of remaining action points. Then, today, I noticed that there is indeed an AP indicator over the character portraits. Something about the outline font you chose made it difficult for me to notice, and indeed it's practically impossible for me to read even now that I know it's there.
Maybe I'm the only one with this problem. But if not, you might want to comp a few different font color/placement/size choices and pick the one that works best.
