The simplicity of the game is highly appreciated from me!
The game flows easily and works very fine!
I dont really feel worried beacause of the low pressure given by the counter, maybe a flashing counter would've worked better.
Also the only problems I can find are the controls and the low readability about lanes and waiting time. I would have prefered different controls instead of A S J and T... is really confusing, and a differentiation of lanes colors and cars, it would have gave me precise informations on what should i do because of the fast pace of the 3rd level.
As I said the simplicity is the key, I really enjoyed it and I can already see a complete flash game with different layers of difficulty, maybe not only given by the number of lanes ;)
