We have the engine running on mobile but we don’t have it wired up to dragonruby-publish yet. Part of the delay is figuring out how to sign iOS applications without requiring all the Mac-specific infrastructure. We’re working on it.
If you have a game you could legit publish (as opposed to “I just want to see if this works,” ...which there’s nothing wrong with either, mind you!) please get in touch and we’ll figure out a way to get you on the App Store sooner while we continue to wrestle with the generic case.
