Small cost for big fun!!
The controls are easy to learn. The view can take some time to get used to since you're not always facing the back of the car. There are many tracks to race on and they're all unique in shapes. There's even a special stage where you race on the moon (with different physics).
The cars aren't particularly nice and neither are the sound effects. The strength of this game definitely lies in the upgrades you'll take and the use of weapons (lasers, bouncing balls, etc) during the races. It's not a very difficult game and it shouldn't take more than about 6 hours to complete. Afterwards, its just about beating your records.
Mini-Car Racing is the perfect game if you're looking for quick entertainment that doesn't much on days where there's just nothing else to do.
