Looking for a puzzle site

Hi,

A while back (maybe last year or before in 2022) I came across a site on this subreddit which I am hoping to find. It is basically a site of puzzles, the main page is a large scrollable image of stars and such in space. Each puzzle is accessed by pressing on where a star is.

I am pretty sure you can't just press any puzzle, but you have to complete close by ones.

Any suggestions would be greatly appreciated.
