Polygons

Polygons are shapes that give experience when destroyed. They can range from the Egg to the Golden Icosagon. There are Green and Orange variants of simple shapes. Simple shapes have dedicated Sanctuaries, which spawn a boss when killed.

List
Some shapes have estimates for HP.

Evolution tree
This tree may not be fully accurate.

''Note: Golden Nonagons and Golden Icosagons are not in the evolution tree, as the Golden Nonagon only spawns from the death of a Golden Sanctuary and Golden Icosagons only come from the evolution of a Golden Nonagon. Black Pentagons are also not included as they are Developer only polygons.''

Lore
Polygons feature in lore, often as the victims of the war against tanks. Polygons appear to be driven by a unique energy, and tanks are supposedly derived from this energy, originally hatching from a mutated Egg. Polygons fear tanks, and created Sanctuaries to defend themselves. However, this rarely deterred the tanks.

The most powerful polygons were the Guardian, Defender, and Summoner, who were corrupted by greed and fused to form the Xyv Wdtcfgzsezgk. It appears that the polygons have been well-defended, however, since the Xyv is often a nigh-omnipotent boss to fight.
