Whack a Mole Challenge

Problem Description

Create a Whack-a-Mole game where players must click on moles as they randomly appear from holes. The game tests reflexes and timing as players try to achieve the highest score possible within a time limit.

Requirements

  • The game should have a grid of 9 holes.
  • When the game starts, moles will pop up randomly from the holes.
  • The player must click on a mole to whack it. Each successful whack earns one point.
  • If the player does not whack the mole within a short time, it will disappear.
  • New moles randomly appear from the holes as the game progresses.
  • The player has 20 seconds to hit as many moles as possible.
  • The game ends when the timer runs out. The final score is displayed and the player has the option to play again.
  • The game should have a start button and display the current score and time remaining.
