  • Prior to an update fixing the issue, Inkwell Hell was instead referred to as "Inkwell Isle Four" on the start-up screen.
  • Inkwell Hell is the first overworld with no Run N' Gun levels or NPCs, and to not have a Die House.
  • It is a much smaller overworld compared to Inkwell Isles 1-4, with it only having two levels. There are mini-bosses in King Dice, which makes it a total of 11 bosses.
  • While the player can progress to Inkwell Isles 2, 3, and Inkwell Hell by only beating the bosses on simple mode, starting "All Bets Are Off!" requires you to have all the soul contracts (that is, the player must beat each boss level on regular mode rather than simple mode).

Inspirations and similarities[]

  • The Devil's Casino is reminiscent of Bowser's Castle, specifically how it's depicted in Super Mario World; "All Bets Are Off!" is located in the casino itself, which is where the Front Door of Bowser's Castle is located, and "One Hell of a Time" is located in the tower next to the main building, which is where the Back Door of Bowser's Castle is located.
  • The soundtrack notably shares the same chord progression as the James Bond theme song. It also sounds similar to Charlie Spivak's cover of the song, Accentuate the Positive.
