It was OK
Good game idea, shame you didn't add more to it though.
I think you should improve the graphics, make them more colorful and make the whole stage a bit more colorful and exciting. The music was fairly plain although clear, and i know you gave a choice, but it was only 2 songs. I think you need to make levels of this where the balls come to you as normal but you have obstacles stuck on the stage to try and dodge whilst dodging the balls aswell. That would make it trickier and more fun.
All in all, a fairly good game!
Well done!
