The demon king built an endless tower over the mortal realm and rules it from above. The only way to end that rule is to fight through every floor of the tower, eliminating the demons defending it until the king can be reached and defeated. A hero has entered the tower with exactly that purpose. The tower does not end quickly. The hero does not stop. A point-and-click game built around reading the moment and striking when the timing is right, with cards acquired along the way that add power to the encounter.
