Some possible improvements could be adding a shop system to upgrade the car. Also the car doesnt go the exact same direction as its facing. Other than that I think you have a possibility to improve the game and make it great.
Reviews for "Turbo Taxi"
My car appears to be drifting the entire time. Why are people in a zombie-filled town standing around waiting for taxis? It appears to be a lame attempt to cover up the fact that the taxi is running over people. Why, when my taxi is running out of gas (nb. running out, not run out) do I suddenly have the urge to drive at half-speed? Makes no sense at all. No pause function! And very very repetitive.
it wasnt much of a good game and kinda sucked
