I'm pleased to announce that Dave Dangerous is now on iOS. This game was ported across to the libGDX framework a few months back. This should have made the transition to iOS easy. However, the Java VM components that are used to run on iOS were discontinued. This meant an alternative was needed. This is now working with the MobiDevelop fork of RoboVM. It's working pretty well.
It's in the App Store, so please give it a go at https://itunes.apple.com/app/id1119322458
Hope to get the In App Purchases working soon.
