I know most people with iPhones/iPads are playing this and thought I'd just share the story
I was saving up my 'awe' to upgrade my shrine and when I went to upgrade it, accidently touched the button that refills the 'mana'. On the off-chance I e-mailed them to ask if they could reverse it. (There I go again.. speaking in riddles I sound like I'm playing dungeons & dragons!)
I got an email back in under 10 hours saying they'd reimbursed me the 'awe' and apologies for the error.
I thought it was pretty nice of them, especially because the game is free
