Ah cool, so you decided for the low-res method. Yes the font scaling is a massive issue there...
But the high res setup comes with some other challenges.

I think it's less important if people care or not. Even if people don't care there is a ton of technical challenge to overcome and a lot of nuance to consider.

I am glad that you enjoyed the article!

Great read! I'm working on a browser based roguelike and basically used the same method you described where the game is lowres and scaled up. It works and looks great but font scaling is an issue, especially on mobile where when the game is scaled big enough to see well the font (5px monospace) becomes too big to fit necessary text on screen.

I thought of maybe including an interface with text readout outside of the game window, so at least there is some separation between where two separate texel scales would be used.

I do also wonder exactly how much people care, it's hard to tell given how picky I've become through doing pixel art.

I am glad to hear that you enjoyed the article and tha tthere was something in it for you to take from it!

Wow, this is a great read! I never considered all the nuance with "pixel perfect", and there was some cool technical info in there too.
