Track the runner. Cast where it will be, not where it was.
Move with your finger, mouse, or left/right arrows. Tap the action button or Space to cast the expanding net downward. It takes time to reach the prey.

What the game helps you notice
Net-casters actively stretch and move a small capture mesh. The game makes reach and interception visible: your net expands during its strike, but the prey keeps moving while it travels.
Why aim ahead of the prey?
During the net’s travel time, the target covers distance. A wider net gives tolerance, but prediction still beats chasing its old position.
A game inspired by science—not a biological simulator.
The overhead track, fixed cast delay, and automatic net return are gameplay rules. This is not a measured reproduction of the spider’s sensing or leg motion.
Try this experiment: What does a wider net change?
Keep cast reach and net settling unchanged. Compare two net-stretch settings and predict how the capture area changes.
