Wish there was an image gallery in-game, also where's the intro?

The paintings that display for the various endings are pretty nice so it'd be nice if there was an unlockable gallery in the game where I could look at them again. I especially think this as I seem to have missed out on the tea party image despite finishing the sea level.

Speaking of art for the game, why is there an intro sequence for the game that obviously took some effort in the trailer (https://www.youtube.com/watch?v=_XI-xK_ts4I) that doesn't actually appear in the game?
