Nice one!
I really liked it overall.
The graphics are great (Metal slug'n'snes rulz!)
The handling of the shuttle is awesome, the braking and nitrous, feels like you put a lot into this part, and the blood on the hood when you run over people (>:D) is just great.
The soundtrack isn't much of a soundtrack... but the sounds (braking, horning) are really good.
Good, and fun game.
