Tried this once again to see if the controls felt any better.

I played for a while, but the “neutral” angle that you have to hold the iPhone at when you don’t want to move feels unnatural to me when I’m slumped on the sofa. I should have checked if there were any calibration options, really. Until I got back and do that, the experiment is incomplete.

Mind you, unless the game goes on sale for half price I’m unlikely to buy it, anyway.
