About 15 years ago there was a cute flash game where you had a little cube world that was a puzzle to grow into a bigger fancier environment by clicking on trigger points in the correct order.

I have no idea what it was called, and can’t describe it well enough to search for it if it still exists. Every couple of years I try.

Resources like this give me hope that little gems and works of art from the past will live on, even if the underlying tech is gone.

Edit:

Wow, this time I found it: https://www.eyezmaze.com/grow/cube/
