Cardinal Quest is finally out for iPhone, iTouch and iPad! Check it out on the App Store!
EDIT: it's now also out for Android on the Google Play Market!
Josh (who is responsible for the mobile port) is watching responses closely and preparing to address player feedback - for example, he is a big chunk of the way through the iPad movement update already.
So if you or anyone you know has an iThing, go ahead and give it a go - we'd love to hear your feedback!
