No, this isn't a controller request. I'll have you know I'm smart enough to figure out how to hook up a wireless controller to Mari0, and it worked as I expected. I booted Mari0 1.6 through steam big picture so it would register my Dualshock 4 and it functioned pretty nicely. Both Mari0 and the controller, DS4 is amazing. it feels soooooo nice.

Anyways, I was recording that playthrough when i took that photo (http://www.youtube.com/watch?v=EY0E884Bx-8), note the obvious fraps number on the top left corner. After playing this way I have a suggeston for improving gamepad control schemes.
I think it would be more useful for a cursor to be displayed to help aim the portal. Like, rather than aim where the player tilts the anaglog stick or presses D-pad, it'll point towards a cursor the player moves. Similar to an iPhone shooter where titling the device moves the cursor, and the game shoots where it is. Also, can an extra button for menu be implemented? It'd be a nice small detail the player can use.
