Slitherine

Summon menu is covering the action area.
Please add a draggable or semi-transparent menu.
Another annoyance: I must select the creature before clicking the summon button, why?

Why should it be draggable? Once you select unit and click to summon it, the window disappears and you can position the unit.

You need to select it because later in the game you will have several different units to chose from.
