Right clicking is a must for the game. You need it to aim accurately. I'm a regular player myself and I think it would be best suited to enable right clicking by holding one of the hardware buttons and tapping with the stylus. If that's even possible. The problem with the d-pad cursor, I think, is that most of the game is done with the stylus anyway. Using the pad only for aiming seems inconsistent Imho another binding should be Ctrl - that's used for picking up items, opening doors and using stuff in general. Hovering the cursor over a door/item/lever will do the same, but it doesn't work well with certain small items or with several items lying close to one another. I'm sorry that I can only offer theory here, I'm not a particularly able programmer.
