Happy Holidays Zaxxon!
I'm on iOS 9.2 as well... In addition to your discoveries, a twitter user helped me track down a lock-up bug that occurs when using certain items in the inventory on the last move of your life (a monster hits and kills you as you wield a new weapon for example). I think this has actually been an issue for several iterations of iOS, but it's rare enough to trigger that I'd never figured out exactly what caused the lockup until @STG_LOVE helped.
I am absolutely considering a new version, and have addressed a couple bugs in a test compilation here over the holidays. The elephant in the room right now is the fact that some things that were OK in the old days are no longer supported and/or accepted in the app store
That means I need to modify a lot more than "broken" items in the programming before RT will pass the modern App Store review process. Since a lot of code needs changing anyway, I'm also looking at refitting all display code and using new sprite-work I've been saving for a rainy day...
Rather than retiring Rogue Touch from the App Store, I will put effort into this overhaul and bug-fixing in hopes of getting another 5 years of life for Rodney the Rogue!
My timetable is uncertain as of yet, but I'm on the verge of shutting down my consulting business... which means full time game programming likely for me 2016
