Description from the developer
You are a ball. There are other balls. You have to shoot them. Survive. Get stronger. Go further. And most importantly get the highest score you possibly can. Designed to be simple, relaxing, and easy to pick up, but surviving for a long time won't be quite as easy as it seems. How long can you survive?
