very cool your game man! the simple design helps not to get lost on the screen and the colors are very well placed with the colorful background in contrast to the dark scenery, and I really liked the screen flip that the game gives, however, I really missed a progressive speed
example: the ball starts slowly and gradually accelerates
and also another tip:
you have to leave a type of reward for the player, like, for your game I indicate a record system there every time you start the game it will be written how far you went.
Other than that I really liked it and it's quick and simple it just needs to add more things. unfortunately I have nothing to give, but I wish you good luck, keep improving and you can go far!😉
