Lumpy

Lumpy is a game about terraforming a barren lava world. You play as an astronaut, using a tractor beam to bring orbiting bodies to the planet and balance its resources so it can sustain life.

Balance the planet

Click on orbiting comets, earth lumps and gas-teroids to change the planet’s water content, mass and atmosphere, respectively. You also need to balance these resources with temperature, keeping them all in their goldilocks zones. Adding too much mass can make the planet implode and undo your progress.

Plant life

When water, atmosphere and temperature are all in their goldilocks zones, right-click to plant a tree. Each plant stabilizes the planet and brings its resources closer to the goldilocks value, but planting becomes progressively harder. Plant five trees without losing one to win.

Score your mission

At the end, your score is based on how long you took to finish the planet, how many orbiting bodies you used and the planet’s final mass. The scoring follows golf rules, so lower is better. Lumpy began as a Global Game Jam 2020 project and was later revamped and expanded.
