First Law

First Law is a 2D platformer in which you guide a probe through hazardous ice caves on Europa and try to make your way home. With little air and icy ground, the probe stays in motion until something stops it—including you.

Control your momentum

Manage the probe’s linear and angular momentum as you move through the caves. Even a slight bump can make you lose control, and one mistake can send you back to the beginning. The controls are simple but hard to master, with sensitive gyroscopes.

Hazards and challenges

Avoid obstacles such as giant snowballs and gravity-wells while collecting terminals. The challenges grow increasingly difficult as you try to escape the ice caves and return to Earth. The game uses retro pixel art.
