This game is good and you have to collide with your opponent, alongside the obstacles blocking your way. You have to defend your place and I love that I can also upgrade the vehicles. For every win, there will be a reward (yay!). I just had a problem with this game, when it suddenly restarted, and I can't play it anymore. I hope this problem can be fixed soon. The graphics of the game are good and this game is one of my favorites.
