Revenge of Doh differs from its predecessor with the introduction of "Warp Gates". Upon completion of a level or when the Break ('B') pill is caught, two gates appear at the bottom of the play area, on either side. The player can choose to go through either one of the gates - the choice will affect which version of the next level is provided. The fire-button is only used when the Laser ('L') or Catch ('C') pill is caught.
