Needs a scoring system and some sort of menu. Also, when the ball goes past you both paddles need to be put back in the centre. A background would be nice, as would having a single colour as the paddles instead of the horrible rainbow colour. Also you are very far from the bottom of the screen and the AI is touching the top, they should be even distances away from the edge. Thought I'd give you some constructive criticism after everyone has simply replied 'IT SUCKED!!!'
