Really cool game! The physics in this game look really well tuned. I kinda had a hard time moving the ball around, mostly when it started nearing an edge of the screen. I think it's mainly because the dragging of the velocity vector seemed to be relative to where the ball was on the screen? Overall really fun, I can imagine getting really good at this game by knowing all of the perfect vectors to draw to get all the particles with the fewest moves possible!
