Ball Grinding Method

Info
The Ball grinding method refers to when you stack up on tons of thousands of balls (via the Random Rooms Glitch)

Suppose you get a Break Point (or some other stage with more crystals than obstacles), and then enter the next stage. Keep quitting, closing the game, restarting the game and then briefly pressing Resume (otherwise you will return to the Main Menu), then wait for another stage with many crystals. Keep doing this, then you will eventually have thousands of balls.

Or, you can just cause a Repeating Checkpoint Glitch, and then smash the crystals, obstacles, etc. Then you will get more and more balls. (see the video)
