Organon

Organon is a first-person shooter. The player can freely move within the
cube-formed bounds of the level. Within those bounds are a number of cubes,
called organisms, which are come in two colors: one depicts good ones and the
other bad ones. Those are stationary, but occasionally teleport around. Every
time the player collides with an organism, health is lost.

The goal is to destroy all baddies without shooting the god ones. After the
deed is done, the player receives points based on health, how many good
organisms were shot and time.
