When the game was a few months away from beta, the game was cut in half. The cut content was intended to be used in a sequel, which never materialised.

The name of Christopher Lloyd's character Drew Blanc (Mal Block in the German version of the game) is a reference to Looney Tunes voice actor Mel Blanc while being a pun on the phrase "drawing a blank". Meanwhile, Flux Wildly's name is a homage to the Flux Capacitor device from the "Back to the Future" film series, in which Christopher Lloyd plays the character of Doc Brown.

Some unused content that was going to be used in the scrapped sequel is still referenced in the final game. The second installment would have had Drew Blanc and Flux Wildly traveling to the "Train of Thought", where they would meet an animated version of Vincent Van Gogh and have an encounter with a nightmarish dentist. In the opening for the first game, Drew receives a phone call reminder to get a dental filling, and a picture of Van Gogh can be seen on the wall in his workspace. Footage of the animated Van Gogh also appears in the official trailer for the game.
