Controls are more or less customizable on PC. You can edit the controls by going to the Steam install directory, then go to steamapps\common\limbo\ and edit the settings.txt file.
Arrow keys = movement
CTRL = move objects
Colors are mainly black and greyscale palette.
Sometimes the black player figure melts into the black foreground and/or background.
Important graphical elements are white.
Additional Info Edit

Windowed possible (here’s how)
OSK works but because often there are two keys to be pressed at the same time, it is not really possible without additional accessibility solutions.
VAC speech recognition not tested.
