Stereojo is a puzzle platformer where you have the ability to look past the environment, and interact with the illusion. Don't understand what that means? Put your index finger in front of your face. Focus on it. Now keep your finger there, and focus on something else in the background. You see two fingers now, right? Stereojo takes that double vision effect and the player uses that to his advantage. Still don't understand? Play the game and you'll see what I mean.
