Blockbuster (also known as Impact) is the usual arkanoid, similar to thousands of other similar games, so describe it in detail makes no sense.
Just "shoot" the ball Bouncing off the platform on clusters of blocks, some of which are indestructible, and some give bonuses, which can 'activate' and get on time some kind of special ability for the ball (for activating some abilities need a few bonuses).
The game has a lot of levels, a built-in editor. The graphics in these games, of course, is not usually evaluated, but it is worth noting that there is a cute "space" backgrounds, and is usually presented in the form of any geometric shapes. Overall – just a game designed for lovers of such amusements.
