So I started with (not so) grand ambitions of walking through the process of reviving Acquisition. What actually happened was a few flurries of activity which eventually got it working again across all device sizes in a way that will hopefully hold up. The only real pain point in the end was fixing the iPad issues. Since I couldn't change from a universal app to an iPhone only one (intended as a temporary fix since resolving the iPhone issues was slightly easier and would ensure that everyone has a working version) I had to get it all working in one go.
The most important thing is that it's working properly, again (and has been for a couple of months now). So far, no crashes.
You can download it from the app store.
