You just successfully disproved my earlier assumption that this used optimizations specifically for isometric views! It actually uses the WebGL for the 3D part too (having said that, such optimizations would still have helped in the hypothetical case one might have wanted to implement this on old hardware) Also, on a desktop you can use the browser zoom (via the menu) to get it to increase the font size. I managed to get my HD screen to show 96 x 54 characters, which comes close to the resolutions on old DOS terminals I think. Now if only it came with a CRT shader, like this one by Timothy Lottes: https://www.shadertoy.com/view/XsjSzR https://www.shadertoy.com/view/XsjSzR
