Super Smash Brothers

Background

  • In Smash Bros, players “smash” each other until one player sustains enough damage that they get knocked out (KO).
  • The exact limit is random, but usually somewhere between 100% and 200%.

Problem

We’re going to create a simplified 2-player Super Smash (SS) game in which ** Users gets to input their names ** Each player is given a random damage limit between 100 and 200 ** Players take turns smashing each other until one player exceeds their damage limit ** On a turn, a player can choose ** a risky smash (10-40 damage) or ** a sure smash (25-30 damage) ** First player’s hits are discounted 5 to make it fair
