Have you tapped mansion in the center of map? End the round button should be there.
And don't skip tutorial. The game is complicated af, or more like unintuitive af.
It's cool that dev integrated some hot scenes without cg's to tutorial, but it's not cool that you even need said tutorial for a porn game to understand how and where send troops every round.
Without kind soul sharing "Completed" 0.38 with all scenes I probably wouln't even bother, but gallery promises enough hot scenes now to deal with wannabe warcraft clone or whatever it is.
