Once it is completed, it does not go through the endgame slideshow :( but it keeps changing to the next levels. After flag click: Space for next slide, right arrow to skip. Main menu: Play to play, Options for sound. Options: Click Help for other instructions. If the portals don't work, stand in them for a few seconds.
All by me, music composed with note blocks by me. @venomous-squirrel : One look at his "Don't click the button" project ( http://scratch.mit.edu/projects/24544686/#player ) had me decide to make a game about buttons. @EPSON508 (not here yet) : Kept me going during the 12-18 hour production time.
