Game Premise

An artificial life simulator which explores the notions of symbiotism and parasitism through cooperative and adversarial multiplayer gameplay.

The first player controls an avatar with the keyboard, while the second controls a cursor with the mouse. As the first player evades predators and seeks prey in order to avoid starvation, the second player manipulates the predators and prey within the environment to the first player's detriment or benefit.

Global Game Jam 2012

Cycles is a two player cooperative/competitive game about predator/prey relationships. Made in 48 hours for the Global Game Jam in 2012. The theme of the jam was "Ouroboros" and, as such, this game is about the continuing cycles of life and death between hunters and the hunted.
