Saw your post on Something Awful, thanks for saying really nice things! I know you're waiting for the game to hit iOS, we are too
The iOS porting will start as soon as the game is complete and out on Steam. We spent a lot of time this last GDC talking to a bunch of really experienced iOS developers on the best ways to make DD work well there.
It's vaguely ironic that right now we're not even Apple registered developers due to a bunch of extremely fun legal bullshit around company registrations and information that we need to give Apple that our company registrar here in SA only gives certain kinds of companies, except they're taking months and months and months to upgrade us to that specific type of organisation. Great fun. If you're an extremely slow-witted masochist.
We will fix all that and we will release the game on iOS as soon as humanly possible.
