Nicely done! Love the rotation at the start and how it seamlessly blends into the level start, not too long and not too short. Gives me Wave Race vibes which is awesome. Only nitpick is the tilting of the camera made it hard to see / felt too strong, though I also get the balance needed to show to the user their input is working. While playing I figured it was meant to be representing the tilting of the whole level itself, but then in one level I saw it made a difference how you sped up being tilted in the air, so perhaps it’s mean to be the cat in the ball? if so, another idea could be to do some visual effects inside the ball to also help accentuate the current tilt/movement input, allowing you to do less of the screen tilt. Just some game ux thoughts as I have ’em! Nice work getting sound and so many levels together.
