If we ignore ctx.font to start with, we don't need to worry about font size or a specific font, as terminals generally use the same font and font-size for everything.

I started testing drawille in my snake game here:

https://github.com/avindra/snake/blob/b7604e1c189ae160e76c06f3d53b35a89aa44baf/Makefile#L13

I might take a stab at it if I get around to hacking more snake.

👍 for this. It seems to be an easy task looking at how asciimoo/drawille does it - https://github.com/asciimoo/drawille/blob/166fe0ceed4c13ab0c25505fd9dd72e9e7b56d66/drawille.py#L168-L177
