Huh, I wrote a very similar game a while ago. Select elements with CSS selectors to get to the next level: https://select.pink/

Mine displays the elements as nested blocks, instead of printing a tree.

Thanks :)

I actually posted https://select.pink/ to HN ages ago, but it died in `new`: https://news.ycombinator.com/item?id=24959045

OP's game has some nice features. The timing is neat, and to be honest I didn't even consider using the source as the visualization.

Wow, nice. I like this even better then the OP. In particular how the levels naturally progress and how the game actively teaches concepts.

Awesome stuff! I learned a few new selectors, thanks :)

Thanks for sharing, learnt a few more CSS selectors.

This is terrific! Do note that IDs are document unique. I found a duplicate id on the `#pan.cake` exercise.
