Really nice game. the concept and idea is awesome, it reminds me of an old flash game (but a zombie apocalipse). I also love that it isn't mandatory to drive and play at the same time., because it would had made the game to difficult. The game is nice and all, but I found 2 inconvenience with this game :
1.The color is white and when I played the game it was during the night so I had to decrease my display light level, because it was a bit too powerfull for my eyes.
2.I observed that if you do left all the way you can see the arm that isn't connected to any body part, just floating with the wheel. (I won't say that this is a problem but it was funny for me) :)
3.The game can improve, because at the moment it is too plain and a bit boring... It would be nice do get from the points collected money to upgrade your car and eve add a booster that boost your car for 10 seconds and recharge in 5 minutes (also, during the boost you are invincible and there is also an upgrade that decrease the cooldown time for every upgrade).
4.The countinuous sound of the car's engine get boring after a while so to make it better I highly suggest you to make possible for players to listen to music from the car's radio.
So that's all I could come up with about problems and improvement in the game. The game in stis stage is already well done, but if you want to get more players maybe a few improvements need to be made. I enjoyed the game and I give you credit for that. Good job! :D
