This is a nice concept and the execution is not too bad or too great. I liked that the colour palette is handled with care so as to make the important parts stand out with contrast, while also making the visual experience not too overwhelming.
Here are a few things that come to mind-
1. Difficulty curve- I had to retry the first level as many times as I did the latter levels [Mainly because the rotation was slightly faster than what I would consider a reasonably challenging speed; the ball did not fly off in the direction I was expecting it to when I tap on the screen]. I see that you did gradually increase the complexity of levels but it would be nice to have the beginning parts a little easier. (I managed to play up to 3 or 4 levels)
2. Green squares - As far as I could notice, the green squares in the level did not seem to have any specific purpose besides adding variety to the visual. At first, I thought these were solid walls that would block the ball. You may want to do something to make it obvious, besides changing their colour, that they are not going to interfere with the trajectory.
3. If you make a post jam version, you could add more depth to the gameplay variety by adding
a) specific type of walls that will bounce the ball.
b) spinners that never get destroyed, or get destroyed after specific number of uses - this can be useful if you want to add a puzzle element, so that the players need to use the spinners in specific sequence or more scarcely to get where they want to go.
(Obviously you will need to playtest to see whether these mechanics are working well. I just shared them from the top of my mind)
The game is fairly decent and has good potential that can be achieved with further polish. Overall, nice work!
