Help me understand the Jebus generation:

On the map, Red only has 1 town. Red and Blue's starting areas are connected by a passage without guards (at the top right, near Blue's town). Because both are on grass, it's hard to tell in a real game when you've crossed into another zone that you're not supposed to enter according to the rules (especially if you're playing as Blue). What is this nonsense?

P.S. By the way, why can't I load save files without an archive (.GM1)?
