Aim Productions has released a new game by the name of Space Balls. From the looks of this game, it is somewhat similar to Zuma.
An incredibly addictive concept, easy to control and hard to put down. Shoot the colored space balls with your cannon, before they smash into your planetoide. If 4 or more balls of the same color touch each other, they are annihilated. Use this to your advantage and try to survive as long as possible!
The game can be purchased from the Developer's site for only $4.99. The game is available to purchase, however the site still lists Space Balls in it's Coming Soon section.
