Timed games that end after a short play and make you start over are tedious. The only reason this game design came about was to get arcade gamers to put more quarters in the machine. Levels would be much better, each one having a different landscape and nemesis (in addition to the cop and biker). It would also be good to be able to run these guys off the road or elude them for extra points. Landscapes could include cities, forests, commercial strips, Vegas, bridges, and tunnels. Hazards would also make things more interesting, like cliffs and rail crossings (beat the train).
Once you play this game a few times, boredom sets in because there's nothing to look forward to except more of the same.
Contrast this to Mobigame's Perfect Cell: high quality, atmospheric graphics, sound and music, self paced, no pressure, high variety, easily achievable levels, extremely high replay value, and a good story and conclusion. On a narrow 5-star rating system, the difference in quality between the two games is too great for this to earn more stars. It's fun for a while, but in the end it's just a so-so arcade game.
