As far as visuals are concerned, Shooting Blocks is pretty static. While there is a foreground where your blocks appear and a background, they are pretty much the same throughout the game's 50+ levels. The overall look is that of a winter wonderland, and since the blocks you are breaking look like ice, I guess that's a fitting theme.
The game's background music and sound effects do their job, but aren't essential to the overall gameplay. This, of course, means you don't have to have it on in order to enjoy Shooting Blocks, a must for any game you might want to try and sneak some play-time in during work hours ... not that I condone such activity, of course.
