Okay
The game is okay but the physics aren't as good as what I've often seen in other Flash games, and the cars don't seem to have the right weight. Also, there isn't enough control over what you do, you can set the ramp, but that's about it. All you can do is press the mouse button nonstop, it doesn't require any thinking. Plus even if you press the mouse button all the time, it doesn't feel like the car is accelerating enough, it seems way too heavy. Also, something I found very annoying is that you have to do everything with the mouse. That scroll bar is also quite annoying, maybe you should find a way to do all this with the keyboard, like accelerating with Space, changing the ramp with UP and DOWN, scrolling with LEFT and RIGHT.
