It's called Keyboard Drumset ****ing Werewolf.
Done by Cactus, an indie games developer who makes the most weirdest and uncomfortable games to play.
This was just pure wut.

Apparently, you play as an Eskimo and something something you're a werewolf and things happen.
I'm not kidding you, I don't understand it either.
Try it out for yourselves before checking out the video (and thus ruin the experience).
Won't even take you 5 minutes to play through the whole thing.
