A lot of potential here!
There was a lot of things that could be improved, but what was basic, was fine. As I said, there is a lot which could be added; multiplayer, high-scores, time attack mode, diff. modes, settable final score (points needed to win). With the high-scores table, you would have to add a timer and points needed, like fastest to get to 7 points, etc. I hope to see this game again as Air Hockey v3!
