The objective in each section of caves beneath the surface of Mars is to establish a functional ecosystem by planting seeds and growing complimentary exotic plants. Controls are intuitive, adapted to the PC (WASD to move and the mouse to aim). The cave sections are somewhat open-ended in where you can plant, and you can certainly create a non-sustaining or overly hostile ecosystem. Waking Mars also occasionally relies on more traditional platform level design (jumping, shooting) that are less interesting overall. Your health can be impacted by hostile plants or other obstacles. Overall, Waking Mars is an innovative game that offers something different than a typical platformer.
