Simple gameplay which worked kind of well, but I personally found it too easy to fall straight to the bottom and die. couldn't really see the theme in this one.
The way I thought the theme was implemented was the following:
Size matters if you want a higher score!
The idea was that you had to change sizes in order to be able to collect more stars and, as such, the size of the ball matters if you want to get more points. But thanks for playing!
