The square is the player of the The World's Hardest Game series. It is a red (in TWHG1; in TWHG2 and higher, the player can change its color) square that needs to avoid the circles.
- The square was only revealed to be a sentient character in TWHG3.
- TWHG2 level 36 or TWHG2.1 level 45 is the level that has the glitchiest hitboxes with the square and the circles. The player can either pass through them or die like a circle was invisible.
