The first challenge that was presented to me in this game was getting oriented to the controls of the paddles. I'm glad that the instructions were clearly written, otherwise it may have taken me a bit to figure them out. You need to coordinate the movements of the paddles, and the physical movements of your fingers on the both the keyboard and the mouse. The ball, or potato rather, was moving very quickly as soon as you got into the game. I scored very low in the first couple tries because I had to spend some time orienting myself to moving the paddles. Once I had that part figured out, the next challenge presented itself. It was not only the different controls of the two paddles, but the way in which they each moved, that presented a challenge. The right paddle simply moved where the mouse went, and you could stop it at a specific point if you stopped moving your mouse. But, the left paddle would continue to move up or down until it reached the edge of the window when you pressed the W or S key. As either of these challenges makes the player lose, the counter displayed in the window incentivizes the player to continue to reach a higher amount of bounces each time. It is simple to restart the game, so it's very easy to just continue trying to get more and more bounces. However, there's not necessarily a real downside to losing-- you simply have to try again. This game also keeps players in it and engaged for a long time (possibly as long as they're able to go?) because there are no "levels" or winning.
