Absence of the map in initial game design played a cruel joke on me - there was no place for it in existing UI. I spend some time in fruitless attempts to add an extra screen alongside to progression screen, but in the end I've submit to need of revision initial design. So all the tabs, including a few new ones and the map itself among them, now are switching from the bottom part of the screen, resources shown on top of it, and current stage info was enriched by selected game mode and moved to the stage start button. Thus, the map tab is finished - that's where stage and game mode selection now happens. It also shows current progress - as you move through story mode and unlock new stages, the paper and ink version of the map blooms with bright colors.
