...has been submitted. F-M-N now works on devices running iOS 3.1.x.
Fixed some other little bugs as well, and added a swipe sensitivity option -
A few people have said they're not getting on with the controls. I originally made it really sensitive because it felt best to me. I tend to play a lot of the time by resting my finger on the screen and only moving it very small distances - like it's resting on a miniature invisible joystick - rather than doing normal swipes.
So if it feels too fiddly to you, try a lower sensitivity once v1.0.1 comes out :) (sensitivity 3 is the highest and default setting, and the same as what v1.0 uses). This is just a small quick bugfix update though.. I'll add more control options later.
