Rotate CW - [>] or hold left side of screen Rotate CCW - [<] or hold right side of screen Sorry about the horrible quality. See for yourself, the arrow is in Vector Mode.
This is just a small test for my first big game, BITly. This will be a computer and mobile-compatible game. This control has some very smooth rotation transitions. With your finger or mouse pointer, drag it left and right across the center; the shade constantly detects where your finger is, and will smoothly transition to the necessary direction.
