Mm, most of those sound like they would just add complexity, rather than fun. You find the optimal raking and then a squirrel RNG scampers across the grid? Fluid mechanics can be fun, but I have no idea how I would integrate them...

If you have ideas, you could try vibecoding them and see if they work. The page should be fully self-contained and have everything an agentic LLM could need.

I have a real garden, no need for the virtual one :)

Core mechanic was that you have to achieve a defined end state and the interactions can help you to do so with additional complexity.
