2D Paintball

A president of a company and his executives are conducting the weekly meeting in their office, but they can't concentrate since there are some smileys that are there to annoy them.  They hire you to rid of those pesky smileys. Use your paintball gun to shoot those smileys before they annoy the executives of a company.  You need to get a 70% accuracy to get through the next level.  The game is played with a mouse and you would need a quick reaction to make sure you get those smileys.  Those executives are not playing so you need to be serious at what you are doing.
