@Entity1037, you press left or right arrow, which ever side the black square is on the bottom line. After selecting correctly, the rows are shifted down, dropping the bottom line. I would suggest a timer to this game with score being based on points per time.

It is a good idea, you will try to challenge yourself to see how fast you can do it. Instead of a simple count down until end of game, have a count down that gets smaller and smaller, if it reaches zero then you will get 0 points for the current selection. So you are forced to move faster and faster as you progress.

Not sure if I can fix that as it is a matter of how fast it reads your key and how fast it does the actual action. I will look at it tomorrow.
