that game looks terribly hard
I love it
Really nice game idea!!
But could you maybe add a little bit of physics to it? So the white areas dont directly add speed, but rather acceleration? so you get faster and faster on white ground, and slow down until you reach regular speed again once you touch grey ground?
That sould make it easier for the player to react in time
(given you can't stop the ball from moving at all, only steer it)
