Midterm Game final reflection for "Pond Balls"

The "Pond Balls" game is a game in which the players goal is to click the balls as they make them selves visible.  There are three levels to the game.  For level 1 the goal is to reach a total of 25 points, for level 2 the goal is to reach a total of 50 points, and for level 3 the goal is to reach a total of 75 points.  The blocks that were used are as follow:

• When green flag clicked 
• set x
• set y
• show
• when space key pressed 
• hide
• forever (repeats an action forever)
• wait ___ secs 
• when this sprite clicked
• change score by 1 
• change score by 2  
• when down arrow key pressed 
• switch backdrop to __________ 
• stop other scripts in sprite
• set score to 0
• say _______ for __ secs
• When I recieve ________
• If _______ then
• ___ = _____
• score
• when right arrow key pressed
• when left arrow key pressed

Some of the problems that I hade to fix while making the game is making sure that the game will level up at appropriate times.  So instead of having the levels in the game change automatically, the levels change when certain keys are pressed by the gamer, with directions on the bottom of the screen of when to change.  For the game to begin its directions press the green flack, to start level 1 press the space key, to start level 2 press the right arrow key, to start level 3 press the left arrow key, to enter the win screen press the down arrow key.
