Old retro pixel art games are best played with a slight blur. I just worked out a hack for myself regarding this. I set up OBS with a full screen record, and added a blur filter to the capture. Then have a preview show fullscreen on my secund monitor. It is a clumsy setup. But worth it. The blur does wonders for the old pixel art. Everything looks so much better.

If the devs are reading this, and there is somehow still possebility for new updates, please consider adding some blur.
