It turns out there ARE HotKeys but it is not announced ANYWHERE and there is no Settings menu to adjust these keys or a way to make these hotkeys visable in the game itself as an overlay (like you would with Bluestacks)
- To add to this, there is no arrowkey navigation, which is a huge miss in my opinion
