iO is an abstract Puzzle Platformer where size, speed, mass and momentum are the notable factors. Players have to constantly change their size in order to solve some of the trickiest puzzles. Increasing your size will make you roll and drop faster; while decreasing it will help you gain height and fit through certain areas. Play with the laws of physics, reach your destination as quick as possible and grab that gold medal as your reward!
