Uh, cool exactly what I need for my ascii file tilemap experiments. But I had a bug, where often the color of the charactes was drawn black until I clicked elsewhere. And I wish I could customize the size of the canvas.
I chose canvas sizes that would be approximately the same size in the window. For the next iteration, being able to choose any size canvas will be a priority.
I use the newest Firefox. But this one is on me, I just checked again and I use a plugin to change every page into a dark mode. When I disable the plugin for you page, everything works fine. Sorry ...
