i feel like it had more potential
it's good, dont' get me wrong, but it could be a 4.3 instead of a 3.6.
the speed cameras seemed too difficulty to get past, i'd slow down, try to goose the throttle through and end up momentarily passing above 90 just because of gravity. eventually i didn't even bother, because it looked like all they did was take some money away; money that i would save by getting my fare there faster.
upgrades would've been a great idea to prolong gameplay, but then you'd probably have to make more maps, too. collision detection, while efficient, was a bit strict at times, and some of the background/foreground objects were hard to distinguish.
not a bad submission, by any standard, but a few tweaks here could go a long way.
