Sorry mate but....
Shall I be honest.. this game is complete crap! one person can go completly out of view and not know where to go, the handling of the cars is very basic theres not even a brake to do drifts and stuff, your cars can go through everything on the map (nothing is a solid object) and the map is so tiny its just not funny...seriously why did you even bother posting this...
Graphics 6/10
Gameplay 2/10
Sound 4/10
My suggestions:
1. Having spilt screen so both players can clearly see where their going
2. Making the cop have to touch the robber for a certain amout of time and have a health bar sort- of thing.
3.Having things to run into and add crashing sound effects.
4. A bigger map with walls to prevent you going into the white abyss.
5. Fast-paced music that actually suits a car chase...
If you work on this you can make it a really good game I love the concept just..well yeh you stuffed it up...
