That much I know but I dont recall the game having any stylus/touch screen control schemes unless I missed something
All Wii U games designed to work with Gamepad use Stylus for menu function,GUI e.t.c.
Sonic Runners on Mobile uses OLED only for controls. Because of this, SEGA designed a special "Two Way Trackball" function that allows both foward movement with a single roll of your index finger, and a GUI 360 circle function that allows users to balance interface for the configuration on the screen.
Perhaps had Gamepad been design with OLED, SLW could have properly utilized this function.
What I was saying is that, with the PC port and remaster, an Ultrabook can FULLY utilize these features, thus SEGA likely may have been able to add this to the PC version.
