I kept getting a score of 1 because the ball was very hard to control at first. Although on my 3rd playthrough, I managed to figure the game out where I got a score of 41.
Anyway, the player playing as the rolling ball in 2D platformer trying to keep the soccer ball on the platform while not falling off yourself is a neat layer of challenge for the player.
There are also "broken" platforms which do work and are amazing to keep the player engaged on getting the ball and yourself in a safe platform.
The art is very good for a basic game, nice work.
I would make a small recommendation of the one button that I felt was problematic. The animated play button in the main menu, I would reduce its scale for x and y at the same value because the play button is large enough that it could have been offscreen.
Don't worry, I've been known by other people that I have a great understanding of UI design and place UI elements somewhere where I know the player will very likely look at. And while that play button wasn't badly placed or designed, the scale and the watery-text animation threw me off just a bit.
The try again button was much better in terms of scale and design.
