Cool game I like the idea.
I find the colour of the main ball and the purple ball to be a little bit to similar for me.
Also I can trow the balls back where they come from (up) and nothing will happen
Hey! Thanks!
And 2 very good remarks. I will change the color of the center ball after the jam and add some kind of barrier to the top, so the balls cannot be shot out of the place to prevent this.
Thanks again!
