Hi, yes, you are right, I do the same, I move inner circle almost to bottom, this way I get larger front area and smaller back area. This is good for me. In addition I found more comfortable for me to not enable diagonals for 4way key mop. This is good for doom and hexen. But for duke3d 4th mop type – native with full range. Of course physical gamepad is better for fps games, touch screen is not so “handy” for fps, but I played and finished duke3d and doom well on my phone. And now I often use one button for strafe, I found it very useful.
