Prompt 3: Describe an interesting moment of interplay.
Since this is a two player-game, I asked my roommates to play this game with me. There are many interesting moments. The core verb of this game is to move the wall up and down so that it can hit back the ping pong ball back. And the person who misses it will lose. First both of us were really bad at controlling how the wall moves. It is a bit less friendly for players who use the arrow keys to control the wall movement, because we were both more accustomed to using the up and down keys to control the walls instead of the left and right arrow keys. So when we switched the sides, whoever that uses the arrow keys always lost. But then after a few rounds, we were getting more and more familiar with it. And there is a case where both of us just stopped move the wall around and the ball can still keep bounce back and forth and nobody can win or lose until I move the wall a bit so that the ball can be hit back in a slightly different angle. Moreover, the ball will shoot immediately once someone did not catch the ball and it will shoot from the middle to the other player. It was really hard for us to catch that at first, and I actually still cannot catch that accurately in the later part of the game, so I lost many rounds. However, my roommate reacted quite good to it and he can catch that ball every time.
