Just press the green flag :) First, the rivers draw themselves, then the towns will randomly place themselves near the rivers. P.S. The 'LOADING' sign in the bottom-left will stay up after it has finished generating. This is because I'm planning to add more, so I didn't want to change the code that triggers it to disappear :p
This is a WIP. There are plans to add: - Roads that generate between towns. - Lakes. - Hills.
