Conway's game of life with editable board in React

Conway’s game of life with drawing and board customization features. Click and drag to place live cells.
Careful with large numbers of rows and columns: they are limited to 100, but can still cause a crash. Any feedback is appreciated.

I like that, it’s looking good and it’s working like expected, good old fun stuff!

One little usability thing: at first I tried to set single points just by clicking but that didn’t work, just click and move is working. But it’s not tragic.

Thanks for pointing it out! Fixed the click, also added an eraser tool and custom cursors.
