Use "W" and "S" to control the left panel and the "E" and "D" to control the left Panel. Sorry for the bugs and glitches( The ball doing nothing when outside the panels reach, ect). To play after the ball glitches out of the panel's reach, just click the flag and reset.
Credit to drewlec. I noticed in his description, he said he wanted to fix the game, so since I know him, I decided t fix this so I can give him tips and tricks on scratch. Anyways, press r to reset the scores. That's about it.
