Could be better... Great idea though!
I hate Justin Bieber. Throughout this game I found myself saying "Take that bitch!" but, the gameplay wasn't amazing. You know what I mean? I felt like this should have expanded or at least could have expanded alot more. How about making a very in depth sequel where he is first on a basic small stage and you throw bottles at him and once his health runs out you get to go on stage and beat him with your fists or a bottle. Then he runs onto a bigger stage ( this is saying as he gets more famous we hate him more ), now we have a knife and you know same thing and at the end we beat him with the knife and he runs off to a new stage a gun and shoot at him and then get on stage and beat him with then gun and then when you go to shoot him point blank he runs off. Then the game can change format and turn into a sharpshooter where he is at a huge concert moving around and what not and you have one shot and if you don't make the kill the security he finally has will kill you if you shoot and miss. Then a whole dramatic cutscene of him collapsing after the shot and how all the people scatter and how the Beiber empire fails and then maybe a free mode could be unlocked where you just beat him with an array of weapons. Put all that into a better looking sequel and I will give you a 10 out of 10.
