Well, this one sure is going to bend your brain a bit. Avoider is a puzzle game with a very basic premise. You have to move two colored squares to opposite corners of the screen without hitting any obstacles. The catch? They're movement is locked together, and you only control the blue one. When you move your box, the red one moves in perfectly-synced symmetrical motion. Yeah, it gets convoluted. Though, reading this site, I'm sure you're used to that.
While the concept is great, this game does have one fatal flaw: touchscreens. As you may or may not be aware, fingertips are often attached to hands, which are themselves attached to arms.
