Mars Rover

You control a small rover on a flat, rocky Martian plain. Using the arrow keys, you roll left and right across the screen. Your goal is to destroy all the target objects, like alien eggs or structures, by clicking on them with your mouse to fire. The challenge comes from managing your movement and aim simultaneously; you're constantly adjusting your position to line up a shot while avoiding obstacles. The pace is steady, and the difficulty comes from precision under a quiet, persistent pressure. It feels like a focused, solitary task of remote cleanup.
