How to use the bench (mouse, touch, or keyboard)
- Time: Play runs the populations. Speed goes from ×0.1 (slow motion: follow each birth and death) to ×5. Step runs exactly one season or year.
- Scrub: drag the yellow playhead on the population graph (or click the graph and use ← / →) to go back in time. The habitat changes to match.
- Look closer: zoom with the slider, the scroll wheel, a pinch, or Z / X; drag to look around. Point at (or tap) an animal to see what it is.
- Keys: Space play / pause · → one step · R reset · Z / X zoom · H help.
