This is Inside's secret alternate ending. Don't watch if you don't want that spoiled.
Big thanks to ZZZZZZach for figuring out the process. The sequence is Up, Up, Up, Right, Left, Left, Left, Up, Up, Right, Left, Right, Right, Right.
Note that you can only do it when all of the secret orbs are deactivated, and you can only do it once. After triggering this ending, all the orbs reactivate and you'll have to go find them all again to do this again.
