What the game helps you notice
Triangle weavers preload a web through an anchor line, then release stored energy. Here, charge sets extension; spring energy grows with extension squared, and launch speed follows the stored energy.
Does twice the stretch mean twice the energy?
Not in the ideal spring model: E = ½kx², so doubling extension stores four times the energy at the same stiffness.
A game inspired by science—not a biological simulator.
The upward target course and single launch are arcade abstractions. Real Hyptiotes moves with its web toward intercepted prey and can release in repeated stages.
Try this experiment: What changes when the web starts with more energy?
Keep web stiffness and energy loss unchanged. Compare low and high preload energy, starting each replay at the same phase.
