I'm afraid that would require quite a bit of re-working, and my computer would slow to an absolute crawl rendering it. Maybe there'll be the option of higher-res versions in future, but it would take a lot of work right now.
not even as a pdf? I could make a pdf print really nicely as the txt would be fonts vs pixel art. no worries if you can't I'll still print it without the txt and go from there. Keep up the amazing work tho. I love a beautiful map.
