Super Hexagon

Super Hexagon is a game played by Markiplier.

Game Information
The goal of Super Hexagon is to control a small triangle which circles around a central hexagon (which occasionally collapses into a pentagon or square in the hexagon and hyper hexagon difficulty) attempting to avoid contact with incoming "walls". The game has six difficulties, a set of "normal" modes - Hexagon, Hexagoner, and Hexagonest - and a set of "Hyper" versions of those levels which are unlocked upon surviving for 60 seconds or more on their respective normal modes. After surviving 60 seconds in the normal modes the level will change into the hyper mode, along with changes to the colour, speed and gauntlet patterns of the level. Further surviving another 60 seconds in the first two levels (Hexagon and Hexagoner) will result in a palette swap of colors, continuing at the same difficulty. Surviving a further 60 seconds (in normal mode, this means you have survived 180 seconds), the game will change to the next level of hyper hexagon difficulty. Surviving 120 seconds in Hexagonest will not cause this, but surviving 60 seconds in Hyper Hexagonest will cause the appearance of the game to become as such: Stationary hexagon (top and bottom parallel to top and bottom of screen), black background, white walls. Every attempt on any given difficulty is timed, with the best survival time being saved separately for each level as a high score. The timer resets upon "death" (collision with a wall).
