Its taken me a while, but Im starting to find all the buttons I need. At the end of the day its about scoring points and there are quite a few ways to do that. There are 8 tabs up the top, and tabs 2,3,4,5 and 8 all have ways to score points in them. Your player board also has a lot of points avaliable on it, by tapping on your portrait, then the 'i' symbol on the lower left of the radial menu that pops up. Your player board even has two pages of ways to score points! I think you score points for bridges, but Im not sure without building one, and cant find it referenced in game.
Ive got to admire @whovian223 for his stately play spirit, and still putting turns in even though its hopeless. It looks like you painted yourself into a corner early by upgrading all your dwellings, and I can see how much of struggle it is for you to get out. As you say, I think it will be over soon.
