Button Smasher

"Button Smash is a simple game meant to bring to life the drawings of a fun-loving youngster–that youthful spirit inside all of us. We’ve all had times where we’ve drawn random shapes. Perhaps we’ve even imagined them come to life. This application brings those drawings to life in the form of a game where you have to push the shapes (the buttons) at the bottom of the screen that correspond to the highlighted shapes above. In this game, you compete against yourself and with others to get the highest score and longest chain."
