If you haven’t checked out the Sector 1 walkthrough of Q.U.B.E. Director’s Cut, you can check that out here. For those who have and want to move on to Sector 2, you can see that video below. Sector 2 is much harder than Sector 1 was and introduces the use of a reset button, a green block, and a green ball. As you can see from the video below, it will require much more environmental manipulations to get through these parts.
Spoiler Warning: Obviously there are spoilers here so only watch if you do not care or don’t plan on playing the game.
