Meh...
Honestly, this is one of the least interesting games I've ever played in my life. This is just annoying. I've read in one of the reviews down below that's you're an eighteen year old male, and I have to agree with them that this is very immature for your age, especially if you're saying you want to kill the poor kid. If you have a big problem with him, then just don't pay attention to all the places where you see him. It's not that hard, really.
Sure it's fun to crack a joke about him every once in awhile, but not like this. No, this is just too far. I didn't even smile when I saw this. Not because you're killing a sixteen year old boy, but because this joke is way over used by a bunch of people that dislike him.
Overall, this game would probably be better if you used different pictures, if it was less repetitive and if you had used better graphics. There was no music that could've entertained me, or anyone else that used this game, but you used gun shots. Not even a parody of a Justin Bieber song? Is it really that hard?
He didn't even move around that much other than just randomly popping out of different windows, and you had to click on his face in order to hurt him. That's quite frustrating, to me anyways.
Maybe remake this, but use better qualities instead. I'm not trying to be rude, i'm just trying to help you out with areas you could really improve on. Thank you for reading my review and hopefully you might take some of the advice I gave you.
