I would like to ask that is it hard to implement controls like this to prboom: Accel-control left and right turning (only x-axis) (preferable user accessible sensitivity control) Tap screen to shoot (or key from right side of keyb) back & forward from keyboard (left side of keyb) strafe button close to back and foward so that you can easily use it with accel. Because right now all the FPS i have tried are bit too hard when played on this little keyboard. After 10 minutes I star to dream on full size keyboard and remember how easy it was with those and then i get frustrated and close game Imo the way that i suggest the control might be close to the best way of implementing control in fps.
