Like a space-shooter in cars
It was poretty good. Unfortunately it doesn't really bring anything new to the table. Needs to be a bit more flexible in some ways. For instance, you can drive the cars off the road, which is cool... but it doesn't do anything for you... they can totally drive right over the houses and other objects to the peripheral of the road without taking damage. The bosses that shoot straight backward aren't necessarily more difficult to beat, they just take the repetetive action of swinging out to the side and back in and firing diagonally at them... which just takes longer. In other words, there's not enough variety in many of the the battles you fight, which makes them boring. The road is also a completely straight shot. Which I can understand bypasses a lot of complexity on the part of the coding (for instance, not having to make the AI smarter in its driving), but again, it makes the ride a pretty boring one.
At any rate, it's solid enough, and the graphics are well put together. Just need to work on the content and variety of gameplay to make it something better.
