Immediately after passing the dark area in Sector 5, there is one room with stairs where the entrance and exit are opposite to one other. Although it appears that you cannot pass left or right, there are fake walls present. When you run into either wall, you will enter a secret room. Note: This is the area also needed to earn "BETA Complete Me" and "Push Me To Completion".
After earning "Push Me To Completion", progress further into the room to find a large puzzle that is not what it appears to be. When the purple arrow buttons are clicked you will tilt the entire puzzle. Get the green ball to the hole found on other side of the puzzle.

After earning "Behind The Scene", progress further into the room until a green ball in a shallow hole appears. Press the wall button to spawn a new ball, then Left Click to roll it into the same hole again.
Complete the "PLANS FOR FANS" level in with a time less than 35:00.
