Super Hexagon is a tough game. It's got really simple controls - you spin the a dot to the left or right, to make sure it avoids the walls of a spinning and fast maze that approaches.

It's accompanied by a thumping chiptunes soundtrack, which pulses in time with the frantic gameplay.

Super Hexagon is really original, but the tough gameplay harks back to the early days of arcade gaming, which is not a bad thing.
