Press space to change the slope of the line, and the direction the ball is moving. You can drag the ball wherever you want. (It glitches at the start, but you can just drag it back)
I decided to share my tests, because it shows I'm active, and helps me know if there is a bug. Let me know if you find any glitches. I'm too lazy to fix bouncing on the side of a line right now, it glitches at the start, and speeds are uneven. That should be all the glitches.
