Show HN: A daily puzzle and 90-second brief I built to start my mornings (rootallyai-55dda.web.app)

I built a small browser puzzle based on a graph theory idea I find unintuitive:

You delete tiles from a grid, but the remaining tiles must stay connected. One wrong move ends the run.

I’ve been using it as a short mental warm-up in the morning, along with a very brief daily news summary.

No login, no feed, no scrolling. Takes ~5 minutes.

Curious how others approach it or where it breaks.
