Sweet!
Not a bad game overall!
The game handled just like any other game in the genre, executed flawlessly as far as I've been playing (up to level 30 now). The upgrades are an excellent feature, which I appreciate in nearly every game. The options for the car were pretty nifty, although to be honest, once I picked a color combination after the first level, I never really looked at them again. (There might be some cool ones for all I know =P) The replay-ability for each level is somewhat low, unless you need cash to advance farther there isn't really a desire to go back and revisit any previous levels.
The medals are always a welcomed touch. Auto-save feature is good, menus are done well.
I appreciate the metal music. Very fitting in a game where you destroy people with cars, guns, and explosives.
Can't really think of any bad points. Keep it up!
