A: Well, there’s nobody left to get you in trouble about that Dead Body, or Splattered Blood, plenty of time to dispose of them or clean up, and we think you should just run away as fast as you can from that ticking Time Bomb, so get outta there with your win, and call it a game!
More specifically, Creepers state that they prevent you from winning, “unless the Goal says otherwise.” Being the last one standing when everyone else is eliminated is a new way to win which is outside of specific Goals with specific statements, and the way you win via elimination is simply to be the last person in the game, regardless of whether you have Creepers or not. We will be clarifying this in the rulesheet on the next printing.
