Time for action – tracking the flood

1. Add the following declarations to the Game1 class:

   const float MaxFloodCounter = 100.0f;
   float floodCount = 0.0f;
   float timeSinceLastFloodIncrease = 0.0f;
   float timeBetweenFloodIncreases = 1.0f;
   float floodIncreaseAmount = 0.5f;

2. In the Update() method of Game1.cs, add the following code to keep track of the increasing flood waters right after the timeSinceLastInput variable is updated in the GameState.Playing case section:

   timeSinceLastFloodIncrease += 
       (float)gameTime.ElapsedGameTime.TotalSeconds;
   
   if (timeSinceLastFloodIncrease >= timeBetweenFloodIncreases)
   {
       floodCount += floodIncreaseAmount;
       timeSinceLastFloodIncrease = 0.0f;
       if (floodCount >= MaxFloodCounter)
       {
           gameOverTimer = 8.0f;
           gameState = GameStates.GameOver;
       }
   }

3. Update the CheckScoringChain() method of the Game1 class by adding the following to decrease the flood counter when the player scores. Place this code right after playerScore += DetermineScore...
