According to appbrain this app was released 9 days ago and looking at the ratings it has about 40.000 downloads. You think this is nothing special? @GameLover: If you want to have the same effect, then just ask some popular youtube stars like pewdiepie oder markiplier to make a game based on them.
As crazy as it might sound to those players the games might be good. Sometimes we feel as if our work is the best and others is crap based on what we like. Sometimes we need to step out of our age group and think of what we would like when we were kids or teens. I know its hard to put yourself in that sort of mindframe but it will help you out in the end.
