Nice. The five-tile paint cursor is an excellent design choice, much easier than the single-tile default you get on apps like Golly etc.
What’s the Hypermedia reference? On mobile your About button is unclickable.
My browser froze up so fast when I visited your page. Had to restart my machine.
How crazy that I started working on something similar a week ago.
Question, why does clicking on a single tile cause a cross on a 3x3 to be inputted? (results in that star thing that ends with 4 blinkers) Was this a conscious decision? Or just the result of a vibecoding
Neat! I implemented something similar (real time playing along with GoL) for desktop:
