Sadly, I can't. The way I have cut it in half won't allow me to shrink those borders down. If I figure out a way to do it that doesn't take several hours per map, then I'll do it.
After 2 years of being uploaded, and a year and a half since an SVG was added, I FINALLY updated this to add a better SVG with cosmokim's suggestion to get rid of the thick borders. Now the extra borders are indistinguishable from the regular borders!
Thnx for using a map where the netherlands actually comes close to looking the way it does ! Instead of that weird deformed lump that is on most of the maps of jetpunk, which hardly has anything to do with the actual shape.
