Looking great. Having some context on the pages would be great, I can understand the grass-rabbit-fox dynamics but not clear with the the rest of the simulations. And you can persist the page in query param. So someone can directly sent people to particular simulation with data.

I am adding more context soon.

I will work on the url query param persistence - I know its annoying at the moment

Love this, simulations are great. My nit pick is around how fast these animations are. You blink and you miss it. I can imagine children having more difficult time with this than myself as an adult. (For context I started with the sound animations: The Invisible Dance -- Shape the Wave & The Journey)

will work on slowing it down

I spotted a bug: "The Tiny City > The Web"

You should use the rabbit emoji instead: https://www.compart.com/en/unicode/U+1F407

Unrelated to the question you posted, but how are you testing these PCBs? Specifically, are you using any software architecture for data logging and running tests?
