So the amazing Zayne Black put together the 99%-Bunlde, featuring 13 diverse and interesting Indie-games. Unstoppaball is one of them.
The guys over at Indiegamemag have a good write-up of how this came together. Go read.
The website of the bundle is 99bundle.com, and it can be downloaded for free/pay-what-you-want over at Indievania.
And it was just reviewed by my favourite journalists from Rock Paper Shotgun. They seem to like it :-)
