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

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.
