The gameplay of Sub-Cirrus is based around balancing a set of variables. You need to keep your wood, water, and food supplies well stocked if you want your population to grow. The player must gather rain during the rainy season with a rain collector. You can gather food with a fishing shack. Occasionally, an island will float by, and you can gather wood off of it by clicking on the tree.
The development of Sub-Cirrus was captured by Alex Gilroy and edited into a short documentary film.
