Here is what's new:
★ iPhone 5 support.
★ Archaic kana. You can now choose to study the rarely-used characters ゐヰゑヱ.
★ In-app settings, bringing with it options to hide the time swirl, increase or decrease the pretty explosions, and even erase all your study data if you want to quickly start over.
★ Speed, graphical, and UI improvements.
This update was sponsored by an anonymous group of Australian students who all bought the app together on Nov 22nd. Thank you!
