A head is the cephalic part of an animal, which usually comprises the eyes, ears, nose and mouth, each of which aid in various sensory functions, such as sight, hearing, smell, and taste. Some very simple animals may not have a head, but many bilaterally symmetric forms do. Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nerve tissues concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the interior region; these collectively form the hed.

Hedgehog Abuse Simulator is a Sonic the Hedgehog 2 made by Selbi.More info:A small hack that was originally intended to become a full-fledged puzzle platformer by the time the contest hit, but due to technical issues and many time constraints never made it past the first few test milestones. For the contest, those few assets have been taken and reordered in a short, albeit (hopefully) polished way.There is no real game here, just a couple of demonstrating concept levels as well as an intro cutscene. The only reason why I decided to submit it anyway was because a lot of people told me to, saying that there's nothing to lose, really. But I hope you'll enjoy this short experience nonetheless!

Hercules is the Roman name for the Greek divine hero Heracles, who was the son of Zeus (Roman equivalent Jupiter) and the mortal Alcmene. In classical mythology, Hercules is famous for his strength and for his numerous far-ranging adventures. The Romans adapted the Greek hero's iconography and myths for their literature and art under the name Hercules. In later Western art and literature and in popular culture, Hercules is more commonly used than Heracles as the name of the hero. Hercules was a multifaceted figure with contradictory characteristics, which enabled later artists and writers to pick and choose how to represent him. This article provides an introduction to representations of Hercules in the later tradition.
