Use your cursor or mouse to move the platform. Don’t let the ball touch the black. At the beginning you have the choice of a black ball or a white ball to play with. Click on one to select it, and a large, green tick would appear on the chosen one. I’ve just added an ending and a reset button so you don’t have to press the green flag again. I recently made the ball eventually get faster and faster and I might work on difficulty settings. Hope you like it.
