You will need a second controller, as this game is offline only. I used a move motion controller, which worked fine. The move navigation controller will not work, as you need a 
button on the 2nd controller. Just hit on the second controller, complete the level (I did the first boss, without touching the second controller) and it will pop a moment later.

It's easier to get at the very first level. Just turn on the 2nd joystick and... leave it alone. Complete the level as the main player, and the second player will automatically move to you after some time. Reach the end of the level and the trophy is yours.
