Cocoon - PC - all secret musical sequences & full ending
Cocoon was directed by Jeppe Carlsen, who previously designed Limbo and Inside.
Cocoon's sound design is entirely made up of synthetic noises rather than recordings.
This video shows all secret musical sequences, needed to trigger the post credit scene.
Discovering and deconding those sequences is, according to what i've read around the web, quite a mess; by the way you must find some places in the game where blue triangles appear and understand the message they are hidding..
Many many many thanks to @elmastabe for recording this ending! what he thought about this game? here what he said:
"the game has a good atmosphere, with increasing difficulty, but without becoming too complex.
You learn how to play along your quest, puzzles became more difficult as you understand new techniques.
It has never been frustrating, not even collecting various achievements."
This video is part of the videogame endings database, whose goal is to catalogue and create the world's largest archive of videogame endings! (what an humble and not ambitious project :D)
