Whisper Machine

The Whisper machine is referenced at several points of the game, notably in the levels Whisper, Island and Machine. One of the interpretations is that of an echo chamber, which "tells" Coda that making games is always easy and fun, worthwhile and rewarding; which he seems to expose a level of doubt about in his games.

The "whispers" can be understood as the bite-sized feedback that creators receive about their games, either as personal opinions, internet comments, media blurbs, etc - a phenomena that real-life Davey is also undoubtedly familiar with after acquiring a huge level of success after the release of his previous game, The Stanley Parable. Presumably, like the voices in the head of a schizophrenic person, the huge volume of "whispers" can be utterly overwhelming and confusing, as each person, online or not, tries to make their own statements, without any type of overall coordination, structure or even agreement between the whole.
