Absolutely. Actually, the two player version of Cake Duel is really the way the game is meant to played and around which all the cards are balanced. We're overwhelmed by all the support for people purchasing the Deluxe edition, but please know that you're not missing out if you only get the "mini", which should probably really just be called "the base game."
Playing with four players does require two full decks and sets of tokens though, so if that's more your game then you'll be better served by the deluxe version.
If you leave a note with your pledge (contact button under "sizigistudios.com") indicating how many additional Mini or Deluxe packages you want, we will add them to your rewards. Assuming you pledged the appropriate amount (+$20 per Mini, +$40 per Deluxe, +$35 per Deluxe if you backed on day 1, +$6 per package if outside of US).
