Its basicly pong with a hockey rink background.
YES! I WON! (of course i won, i'm good at pong and I really play hockey.) Well, it isn't as much hockey as it is pong, so that was kind of disappointing. I suggest adding sound. (Ya know, goal horn when you score, booing when the CPU scores, hockey sounds.) I love all the noise at hockey games. Also, you may want to add a "How to Play" page, cause it took me a second to figure out that you move the...thing with the arrow keys, which is bad because the game starts right away and it's important to score the first goal in a hockey game. (maybe have a 3 second countdown before starting the games, so you're ready to play when it starts.) Also, make the 'paddles' look like goalies! The difficulty levels were fair. I guess it could have been worse, but i'd be willing to bet you can do much better. I hope this review helps.
