Crikey, I wasn't expecting this to be as hard as it is!
Reminder to developers : Just because it works with a mouse on your PC, doesn't mean it'll work well with a giant iPad screen or tiny iPhone screen, directly in your hands!

I think the rest of today will probably be about shuffling the buttons on the screen, to try to find something that feels just right..

Also, I might try making an analogue thing, instead of a dpad.
