Mycocosm is an arcade-style plant management game where fungi are fast friends and bacteria will cheat you of your precious nutrients. As a plant, your objective is simple: survive and grow. To do so, you'll need access to phosphorous and nitrogen, two difficult to find yet vital elements. Fortunately, wandering fungus spores will trade you these resources in exchange for access to your carbon. Everything comes at a price, however, and these fungi will take what they can and exploit you where possible. Risky offers will begin to flood in, so quick reflexes and wary dealings will be your only chance against the trading onslaught.

This game presents the concepts of symbiosis between plants and soil microbes, defense against root pathogens, and plant resource storage and collection.
