I'd like to see a couple of things for official iOS/Android controller support that would make enjoyment of the game a lot better...
1. On Android, there is zero deadzone which makes the camera constantly move.
2. Add a lock-on button! Can't believe this wasn't included from the start. L2 is free.
3. Option to invert y-axis camera. It's backward from the standard of pushing up on the stick means look up.
