The very start of the game could use an extra second to get one's bearings before moving the ball. That being said, I really enjoy the movement of the ball. Nicely done. A couple of power-ups and this could be pretty wild.
those would absolutely improve the game. As another commenter said, a small countdown and some indication the platform was going to move would have improved the start a lot.
Powerups I would have loved to nail down for a final submission.
