  • On Mac, press Apple+Shift+4 for a selection window.
    
• FILE TYPE: Save as a PNG or GIF, preferrably.

• Future mapmaker version: Will have a "Save Map" and "Code Map" feature.

These are not rules, but rather preferences:

• HQ to HQ distance:  not more than 11 road sectors.
• GP to GP distance: not more than 8 road sectors.
• TeamHQ to TeamMine distance: more than 1, less than 5.
• Avoid putting road on forest, where it can be avoided.
• Unless its grass, avoiding having more than 3 of the same terrain next to itself (like 3-4 rockies in a row. Dont count hq/gp/mine sectors)
• Make use of as many kinds of terrains, to make the map look more colorful.
• Rivers, Rocky walls, and Mountain walls always come in handy, but aren't always needed. 
• Keep in mind, ground vehicles can travel over non-road sectors as well (on grass and forest), so dont feel the need to fill the entire map with road lines. (It doesn't look pretty)
