only problem i had with the game is that sometimes when there is a bonus achievement say for example "blow up 3 firetrucks", sometimes 3 firetrucks dont appear on the level :\
good initial idea but 1) my "enemy" was on the white sidewalk so i could not attack him until he ping-ponged his way onto the street then he did a flip and flew through the air. 2) drifting is terrible 3) the city is too big to find people 4) the game becomes unplayable when u fall into "the sea"
