Everything. Played through Episode 1 and Superstory of Episode 1.
What does not
In my case when playing with a controller, the second player is automatically activated once I press a button and both players move in unison.
This can be fixed by manually removing the /dev/input/jsX device file of the controller. (/dev/input/js0 in my case).
What was not tested
Playing through the entire game.
