Hey,
Sorry for the delay and thanks for the heads up. I totally blanked on the PC controls and had to make the PC controls' image. It's here:
Also, @goreal, I updated the controller image and in-game controller UI a little bit. The JETPACK and GLIDER button switched. I updated the image above to reflect this change. So to be clear:
GLIDER is LEFT BUMPER
JETPACK is RIGHT BUMPER
As you approach things in the game or gain abilities, Lunchbox, who is the little red robot following you, should tell you what buttons do what and that's for PC or a controller.
One last thing, I updated the UI in the game so now when you press ESC or PAUSE you can see the controller mappings. I'll try to get the PC mappings in there in the next build.
