You are on the left Player. Use Mouse to Control. First to five wins. Use up and down arrows to change speed. Two player version: https://scratch.mit.edu/projects/103008310/ (tip) If you're having trouble or nobody has scored for a while make the ball faster (up arrow). (this will be at your advantage)
This is the upgraded version of the two player version (link above). I used the same graphics and similar code though some glitches were fixed. If there are any comments please say. You will probably have to click the green flag multiple times.
