A very solid game! The soft design aesthetic gives it a very cool touch. Also the sounds are a perfect match.
It's easy to understand and that the tutorial is included in the game and pops up when it's time is very much appreciated in this gamejam where you have to go to the pages to read a text to understand the game.
Maybe the only thing I would change would be that the rebound of the ball would have realistic physics and momentum in the rebound, instead of always bouncing with the same intensity, which makes it difficult to control sometimes.
Overall it is a very complete work, congratulations!
