The game is fun and exciting to play but, the rewards on each race are to few. Also sometimes the level gap of players on each race are quite big (you will meet someone with 2 or 3 levels ahead of you and that means that their car are 2 or 3 more times upgraded than you) that makes it harder to race. Well... it's still a nice game if you're bored or something. Also it would be better if you put a game lobby where you can invite friends to race with.
