Grow your plant using the resources you find dotted around the alien landscape. Collecting energy will awaken the resident plants which pose a threat to your plant health and must be defended against. As you play, resources become more scarce and threats more dangerous. The key to success is to assess where the risk is based in a level, and plan how your impact on the environment will affect your chances of survival. Rizk was created for the Science Museum.
