99 is to easy to get to we need more levels it gets boring since any score you get doesnt realy mean any thing since the leaderboards are hacked. go to like 199 or some thing and make it a challenge to level up.
Or why not just infinite? Kinda sucks that once you hit 99 there is nothing to really shoot for anymore, leaderboards are redundant due to hackers and money loses all it's value after you get your 6th Custom Class. ProTags are still fun to collect and all but that only goes so far and they are relatively cheap.
