in the level "the mainframe heist" it's when you get to the third lock when you see a little smidgeon of touch material on the bottom left corner of the screen. hold your finger on it, wait for the door to unlock, and go to the location of the door. the level shall now END and the scoreboard shall show up

I know this is a few months late, but could you show us the skip in action? I'd like to see how it works while in game.
