I'm still not sure if that was meant to be an art game or a parody of an art game. I suppose, in the end, that it doesn't matter.
To me this doesn't really fit the bill of a "so bad it's good" game. It's more of an experience than a game, for one, and it's really surreal and bizarre, but not in the janky weird way I usually associate with "so bad it's good". It's kind of orthogonal to that whole scale of bad, goodbad, good. It just is.
On the note of the button: I was never sure if pushing keys to activate the button actually did anything or not because there wasn't any feedback indicating that it had been pressed.
