I just upgrade to iOS 9.3 and discovered that it causes some graphical issues with Cursed Loot. I will try to get a fix out as soon as possible.
EDIT: Cursed Loot 1.1 is now available on the App Store. It fixes iOS 9.3 compatibility issues and adds a virtual d-pad by default. (Touch movement has also been improved--disable the d-pad in options to use touch movement, if you prefer.)
